A hackamore is a bridle that controls a horse without a bit. Instead of acting in the mouth, it works through pressure and release on the nose, the chin groove and the jaw. The main types are the traditional bosal, the sidepull and the shanked mechanical hackamore, and each one asks for correct fit and light, well-timed hands.
This guide explains how each type works, how to fit one, where hackamores are and are not allowed in the show ring, and how to choose the right one for your horse and your riding. Along the way we point to the hackamores, sidepulls and bosal sets we carry so you can compare real examples.
Understanding Hackamores: What They Are and How They Work
Picture a piece of tack that lets you guide your horse with nothing in its mouth. That is the idea behind a hackamore. It is a long-standing tool in Western horsemanship, and it rewards riders who use gentle cues and clear releases.
What Is a Hackamore?
A hackamore is a type of bridle used to control a horse without a bit. The traditional form is a braided noseband called a bosal, hung from a headstall and fitted with a rope rein. University of Missouri Extension's guide Pre-Bit Hackamore Training (G2864) describes it as a way to start a young horse before it carries a bit: it "doesn't injure sensitive tissue in the colt's mouth, yet it provides firm, safe control." The same guide notes that the method rests on the principle that "the horse learns to respond to pressures on its nose and under its chin."
Today the word covers several designs, from the rawhide bosal to the leather or rope sidepull to the mechanical hackamore with metal shanks. They all share one trait: the signal reaches the horse through its face, not its mouth.
How Hackamores Work: Mechanics and Communication
When you pick up a rein, a hackamore spreads that pressure across the nose, the sides of the face and the chin or jaw. How it does so depends on the design:
- Bosal: the rein pulls the heel knot under the chin, and the noseband presses on the nose and jaw. The release is what teaches.
- Sidepull: the reins attach at the sides of the noseband, so a rein gives a direct, sideways signal on the nose.
- Mechanical hackamore: shanks and a curb strap act as a lever, adding pressure on the nose, the chin groove and the poll.
Because the hackamore acts on sensitive areas of the head, heavy or constant pressure is uncomfortable for the horse. MU Extension's guide puts it plainly: "Never give prolonged steady pulls on the hackamore." It also warns that severe contact "can cause the horse to overreact to pressures," while contact that is too soft can leave the horse ignoring the cue. That balance is why hackamore riding builds finesse, timing and a quick release.
Comparing Hackamores and Bitted Bridles
Both hackamores and bitted bridles give the rider a way to steer, slow and stop. Where they act, and where you can show in them, differ:
| Feature | Hackamore | Bitted Bridle |
|---|---|---|
| Acts on | Nose, jaw, chin (and poll with shanks) | Mouth: bars, tongue, lips (and poll with a curb) |
| Communication style | Pressure and release on the face | Pressure and release in the mouth |
| Common uses | Starting young horses, horses that are being rested from a bit, riders who prefer bitless tack | Most schooling and showing |
| Allowed in USEF Western classes | Only in limited cases (see below) | Yes, within the bit rules |
Riders often try a hackamore for a horse that resists the bit, or while the horse's mouth is being checked or treated. If your horse is fussy in the bridle, have your vet or equine dentist look at its mouth first, since a sore mouth or dental problem is a reason to see them, not just a reason to change tack.
Types of Hackamores: An Overview
There are four main families of hackamore, each with its own feel:
- Bosal hackamore: the classic braided noseband with a hanger and a mecate rein, used for starting young horses. For a full walk-through, see our guide to the bosal and horse comfort. The Weaver Leather Rawhide Bosal is sold on its own, and complete sets such as the Professional's Choice Rawhide Bosal and Mecate Set with Blood Knot Hanger and the Weaver Leather Complete Mecate Set include the bosal, hanger and rein together.
- Sidepull: a noseband with rein rings at the sides that gives a direct, simple signal. Examples include the Weaver Leather Side Pull with a double rope noseband and the Professional's Choice Round Leather Nose Side Pull.
- Mechanical hackamore: a noseband with metal shanks and a curb strap or chain that create leverage. We carry styles such as the Toklat Zilco Mechanical Hackamore and the Professional's Choice Equisential Hackamore.
- Cross-under and other bitless bridles: designs in which straps run under the jaw or around the head rather than to a bit. They act differently from a bosal or a mechanical hackamore, so read the maker's directions closely.
Each type suits different riders and horses. The bosal is a staple of traditional Western horsemanship, while sidepulls are popular for groundwork, early rides and easy trail riding.
Materials and Typical Uses
Hackamores come in a range of materials, and each one changes the feel and the care needed:
- Rawhide: the traditional material for bosals; firm, with a clear signal.
- Leather: used for bosals, sidepull nosebands and headstalls; needs regular cleaning and conditioning.
- Rope: common on sidepull nosebands and on mecate reins; light and flexible.
- Synthetic and metal: found on mechanical hackamores; synthetic parts are easy to wash, and metal shanks need checking for wear and sharp edges.
Hackamores are commonly used for starting young horses, for horses that resist the bit, and for riders who prefer bitless tack for trail and pleasure riding.
Hackamores in the Show Ring: What the Rules Say
Not every class allows a hackamore, so check the rulebook before you enter. Under the USEF 2026 Rulebook, Chapter WS (Western Division):
- WS105.4 permits hackamores "in any class on a junior horse five years old and under." It defines the hackamore as a rounded bosal of braided rawhide or leather with a flexible nonmetallic core on a suitable headstall, calls for approximately 3/4 inch between the nose and the bosal, and limits the bosal to no larger than 3/4 inch in diameter at the cheek. Reins may be hair, rope or leather.
- WS105.5 lists "hackamore bits, bosals, cavesson type nosebands, martingales and tie-downs" as prohibited in the standard bitted equipment, so a shanked mechanical hackamore is not legal in those USEF Western classes.
Rules for breed associations, 4-H, clubs, trail rides and other events vary, so ask the organizer what is allowed before you show.

Bitless Riding Essentials: Tack, Fit, and Safety
Bitless riding can be a kind way to communicate with your horse, but the right equipment and a correct fit are what make it work. Whether you are new to the hackamore or refining your setup, these essentials keep your horse comfortable and your cues clear.
Essential Bitless Tack
A bitless setup starts with the hackamore itself, which replaces the bit. Alongside it you need a headstall that fits, reins suited to the design and, on a mechanical hackamore, a curb strap or chain. A bosal takes a hanger and a mecate; a sidepull takes a pair of reins clipped to its side rings. Each part has to work with the others so your signals stay clear. Our guide to using mecate reins explains how the rope attaches to a bosal, and for a broader look at what goes on a horse, see our essential horse tack guide.
The Importance of Proper Fit
A well-fitted hackamore matters for both comfort and control. Ill-fitting tack can cause rubs and pressure points and muddle your cues, which can lead to resistance or unsafe moments. MU Extension's hackamore guide says the hackamore must be "placed low on the nose, near the soft cartilage," and that the bosal should be short enough to make both nose and chin contact without sliding up the nose. For a sidepull or mechanical hackamore, follow the maker's directions for noseband height and curb strap adjustment.
Adjust the headstall so the noseband stays where you set it and the reins give light, steady contact without pulling the noseband out of place. Recheck the fit as your horse's weight, condition or coat changes.
Measuring Your Horse for a Hackamore
Measure before you buy. Use a soft tape to measure around the nose where the noseband will sit, and compare that number with the maker's size guide. If you plan to show in a bosal, remember the USEF 2026 WS105.4 limits above, including approximately 3/4 inch between the nose and the bosal. When in doubt, ask an experienced trainer to check the fit with you. A correct size helps prevent slipping and over-tightness.
Safety Considerations and Common Mistakes
Before each ride, check every buckle, knot and fastening. Look for fraying, cracking or stretched holes, which can weaken tack. Common mistakes include setting the noseband at the wrong height, leaving the curb strap of a mechanical hackamore too tight, and missing early rubs. Watch how your horse responds after each change and adjust until it carries the hackamore calmly.
Example: Fitting a Sidepull vs. a Mechanical Hackamore
The two styles fit differently. A sidepull noseband should sit snugly at the height the maker shows, with the side rings level so each rein gives a clean, direct signal. A mechanical hackamore needs careful adjustment of the noseband and curb strap so the shanks act gradually instead of clamping. Always test the fit at a standstill first, then at the walk, and watch for a relaxed head and a soft response before asking for more.
Benefits and Challenges of Bitless Riding
Many riders are drawn to the hackamore because it takes the bit out of the conversation while still giving them a way to steer, slow and stop. Like any tack, it has strengths and limits.
The clearest benefit is that nothing is in the horse's mouth. That makes the hackamore useful for starting young horses, as MU Extension's guide describes, and an option for horses that resist the bit. Some riders also find that working in a hackamore makes them more aware of their hands and of the value of a timely release.
Not every bitless design is gentle, though. A mechanical hackamore with long shanks acts as a lever and can apply strong pressure to the nose, chin and poll, so it needs experienced, quiet hands. Any hackamore that is badly fitted or used with steady pulling can rub or make a horse sore.
There are practical challenges too. Some classes and competitions restrict hackamores, as the USEF rules above show. Riding well in a hackamore takes soft, independent hands and precise timing, and a poor fit can confuse the horse. Education and attention to detail go a long way.
A common myth is that a hackamore always gives less control than a bit. In practice, how much control you have depends on the design, the fit, the horse's training and your hands.
To sum up the main points:
| Benefits | Challenges |
|---|---|
| Nothing in the horse's mouth | Discipline and competition restrictions |
| Useful for starting young horses | Rider skill and timing required |
| Encourages light hands and clear releases | Risk of rubs or soreness from poor fit or misuse |
| An option for horses that resist the bit | Leverage designs can be severe in heavy hands |
| Several designs to suit different riders | Needs a careful, gradual transition |
Weighing these points against your horse's needs and your goals will help you make a fair, informed choice.
Choosing the Right Hackamore for Your Horse
Picking the right hackamore comes down to your horse, your skills and the riding you do. Taking it step by step makes the choice simpler.
Factors to Consider for Hackamore Selection
Start with your horse's age, training level and sensitivity. A young or green horse usually does best with a simple design and a direct signal, while a finished horse may respond to finer cues. Consider head shape, since the noseband has to sit where it belongs without shifting.
Your discipline matters too. Traditional Western riders often choose a bosal, while trail and pleasure riders often reach for a sidepull. If you are weighing a bit against a hackamore, our guide on how to find the right bit for your horse covers the bitted side of the decision.
Matching Hackamore Types to Riding Goals
Think about where you ride most: trail, arena or competition. Sidepulls are simple and suit pleasure riding and early training. Mechanical hackamores, with their leverage, give more stopping power but need experienced hands. Here is a quick comparison:
| Hackamore Type | Often Used For | Key Feature | Consideration |
|---|---|---|---|
| Bosal | Starting young horses, traditional Western | Subtle nose and chin cues | Takes skill and good timing |
| Sidepull | Early rides, trail, groundwork | Direct sideways signal | Less leverage for stopping |
| Mechanical | Riders who want leverage without a bit | Shanks and curb strap | Can be harsh if misused |
| Cross-under | General bitless riding | Straps around the head | Fit varies by design |
Shanked hackamores come in different shank lengths, and a longer shank gives more leverage. One example we carry is the Professional's Choice JC Hackamore with a 6 3/4 inch shank. As with any leverage tack, start with a light hand and work with a trainer who knows the design.
Comparing Brands, Materials, and Budget
Material affects both feel and lifespan. Rawhide and leather offer a traditional feel, while synthetic parts are easy to clean. Look for solid stitching, smooth edges and hardware that closes securely.
Prioritize fit and function over looks, since an ill-fitting hackamore can cause discomfort however good it looks. Compare the maker's stated materials and size range before you buy. You can see the hackamores and sidepulls we carry side by side in our Hackamores and Bitless Bridles collection.
Trying and Choosing a Hackamore
If you can, try more than one style before you commit. Some trainers let students ride in different setups during lessons. Watch your horse's reactions and look for signs of comfort, responsiveness and relaxation.
If you are unsure, ask a knowledgeable trainer to check the fit and suggest adjustments. Patience pays off whenever you introduce new tack.
Example: Deciding Between a Bosal and a Sidepull
Picture a rider with a young, sensitive horse who wants to start bitless. After trying both, the rider finds that the sidepull gives a clearer, more direct signal for groundwork and early rides. As the horse gains experience, the bosal can become a tool for refining cues. A transition bridle such as the Weaver Leather Kalley Horseman's Bridle, sold as a sidepull-to-bit transition, is another way to bridge the stages.
A sensible plan is to start with the simplest hackamore that does the job, then progress as your skills and partnership develop.
Expert Tips for Successful Bitless Riding
Riding well in a hackamore takes skill, awareness and ongoing learning. These habits help you communicate clearly, keep your horse comfortable and build trust.
Developing Soft, Independent Hands
Success with a hackamore starts with your hands. Abrupt or heavy cues on the nose can confuse or annoy the horse. Ride with a relaxed grip, loose elbows and even reins so small changes come through clearly.
Practice patterns at the walk and trot, steering with your seat and legs as much as you can. Relying less on the reins teaches your horse to answer lighter signals.
Reading Your Horse's Feedback
Watch your horse's body language. A soft eye, a lowered head and a relaxed jaw are good signs. If your horse tosses its head, resists turning or seems anxious, it may be reacting to too much pressure or a fit problem. Check for rubs or sore spots after each ride and adjust your tack as needed. If you find sores or swelling, stop using the hackamore and ask your vet.
Training Exercises to Improve Responsiveness and Trust
Start each session with simple groundwork, such as leading exercises and yielding the hindquarters, so your horse understands your cues before you mount.
Once in the saddle, practice transitions between gaits and ask for smooth, prompt responses. Use your seat and voice as your main aids, and save the hackamore for light reinforcement.
Working with a Knowledgeable Trainer
Switching to a hackamore goes more smoothly with help. A skilled trainer can refine your technique, troubleshoot problems and spot fit issues you might miss. Feedback from someone on the ground is valuable for both horse and rider.
Troubleshooting Common Problems
Even experienced riders run into problems. Here is a quick reference:
| Problem | Possible Cause | What to Try |
|---|---|---|
| Head tossing | Poor fit, too much pressure | Recheck fit, lighten your rein aids |
| Evasion | Confusion, unclear signals | Simplify cues, go back to groundwork |
| Weak stops | Not enough training yet | Practice transitions and seat and voice cues |
Many problems come from unclear signals or a poor fit. If they persist, ask a trainer, and see our guide to horse bridles for more background on how headgear fits.
Resources and Continuous Learning
Keep building your hackamore knowledge with:
- Books on traditional hackamore and bitless riding
- Extension publications, such as MU Extension's Pre-Bit Hackamore Training
- Local clinics and lessons
Step-by-Step Exercise: Refining Bitless Cues
- At the halt, ask your horse to flex softly using minimal rein pressure.
- Release the moment your horse responds, to reward the right answer.
- Move on to walking circles, guiding with seat and leg and using the hackamore only as a light reminder.
- Add serpentines and transitions, and keep rewarding light responses.
Repeat this drill regularly. Patience and steady practice are what make bitless riding work, for you and for your horse.
Frequently Asked Questions
Is a hackamore kinder than a bit?
It depends on the design, the fit and the rider's hands. A hackamore keeps pressure out of the mouth, but a mechanical hackamore with long shanks applies leverage to the nose, chin and poll and can be severe in heavy hands. Any hackamore that is badly fitted or used with steady pulls can rub or make a horse sore.
Can I show my horse in a hackamore?
Under the USEF 2026 Western Division rules, hackamores are permitted in any class on a junior horse five years old and under (WS105.4), and WS105.5 prohibits hackamore bits, bosals, martingales and tie-downs in the standard bitted equipment. Other associations and events set their own rules, so check with the organizer.
Where should a hackamore sit on my horse's nose?
University of Missouri Extension's guide says a hackamore must be placed low on the nose, near the soft cartilage, with the bosal short enough to contact both nose and chin without sliding up. For a sidepull or mechanical hackamore, follow the maker's fitting directions and recheck after you ride.
Which hackamore is best for a beginner?
Many riders start with a sidepull because it gives a simple, direct signal. A bosal takes more skill and timing, and a mechanical hackamore needs experienced, quiet hands. Whatever you choose, have a trainer help with the fit and the first rides.
