The Best Underwear for Horse Riding of 2026

The wrong pair announces itself about forty minutes into a ride — a seam that starts as a faint annoyance under your seat bones and becomes the only thing you can think about by the time you ask for a trot. What you want instead stays flat under breeches, doesn't roll down when you mount, and keeps your inner thigh from rubbing raw. Over the past six months, my team and I rode in 14 pairs to find the ones that disappear.

Fabric is where most riders get stuck. Cotton breathes but holds sweat on a hot afternoon; smooth synthetics glide and dry fast, though a loose fit will ride up. Boyshorts and slip shorts cover the inner thigh where chafing starts, but thickness is a trade-off — too much shadows through light breeches, too little goes sheer when stretched.

Fit matters just as much between sizes or in plus sizes, since a waistband that feels fine standing still can fold over the moment you swing into the saddle. The picks below survived the wash and never crossed my mind mid-ride.

Seamless construction is the reason this pair sits at the top of our list. Under close-fitting breeches, a flat front and smooth leg opening do more for comfort than a pretty print or a fancy fabric name, and the YADIFEN shorts keep that profile without feeling like a second pair of tights. We also like the light compression: it holds everything in place in the saddle without the restrictive squeeze of real shapewear.

Anti-chafe performance is the other half of the job. The long boyshort leg covers the inner thigh where breeches rub, and the high-waisted cut stays put through mounting and dismounting. The seamless front means there is no center seam to press against the saddle, which is exactly the kind of detail that matters on a long ride. The fabric is stretchy and breathable enough for summer, and the three-pair pack makes it easy to keep a clean pair in the trailer.

The lighter colors can turn sheer under thin breeches, so we keep this pair in black for riding. If you want zero compression, Reamphy is the better fit; otherwise, this is the pair we reach for first.

Worth Noting

  • Light colors can turn sheer under breeches
Our Verdict

Our top pick for most riders: a seamless, lightly compressive boyshort that stays flat under breeches and helps stop inner-thigh rub.

The no-roll waistband is the first thing we notice about the Reamphy shorts, and it is the reason they earn a place here. A waistband that folds under breeches turns a good ride into a fidgety one, and this pair is built to sit flat without digging in. The smooth boyshort cut also slides under close-fitting breeches without bunching at the leg.

The fabric is soft, stretchy, and breathable, and the leg openings stay put without a grippy band. The three-pack is a practical rotation for riders who wash gear often. They are not as flat at the front as the YADIFEN pair, but they make up for it with a more relaxed feel around the waist.

The lighter colors are the weak point: nude and white can show through light breeches, so treat those as layering colors rather than stand-alone shorts. If you mainly want a smooth, no-roll short and do not need compression, this is the one we keep coming back to.

Worth Noting

  • Light colors can show through breeches
Our Verdict

The no-roll pair we choose when a waistband that stays put matters more than light compression; smooth, breathable, and easy to wash.

Cotton is a deliberate choice, not a default. If you like the feel of a natural fiber against your skin and you are not spending hours sweating in the saddle, the wirarpa boy shorts are the pair we point to. The cut is roomy through the leg, which keeps the fabric from creeping into the crease where chafing starts.

The cotton is soft and gets softer with washing, and the four-pack is a sensible rotation for everyday riding. The boy-short length gives more coverage than a brief without the slick, compressed feel of a shaping short. We also like that the waistband is soft rather than a wide band of firm elastic, so it does not press into you when you sit deep.

The trade-off is moisture. Cotton holds onto sweat longer than a synthetic blend, so on a hot, long ride it can feel damp against the saddle. We treat these as a cool-weather or shorter-ride pair, and we size up if we are between sizes because the fit runs close.

They are also less opaque than the dark colors suggest, so pair them with breeches you trust. If you want cotton next to skin and a relaxed leg, this is the pair; if you need fast-drying performance, go with a synthetic short instead.

Worth Noting

  • Sizing runs small for some riders
Our Verdict

We choose this cotton boy short for riders who want a natural-fiber layer next to skin; soft, anti-chafing, and best on shorter or cooler rides.

Thin and airy is the point of the Yeblues shorts, and it is why they earn a spot for hot-weather rides. The fabric is light, and the no-roll waist keeps them from turning into a folded band under breeches. We like that they add almost no bulk through the seat, which matters when your breeches already fit closely.

The long leg gives good coverage against inner-thigh rub, and the stretch is generous without feeling loose. In warm weather, the thin fabric is a relief; it does not trap heat the way a heavier cotton short can. The four-pack is also useful if you ride several days a week and do not want to run laundry every night. For a rider who overheats easily, the breathability is worth the trade.

Worth Noting

  • Light colors can turn sheer
  • Seams can tear with washing
Our Verdict

We reach for this pair in hot weather: it is the lightest, airiest short here, with a no-roll fit and a four-pack rotation.

The BESTENA four-pack is the budget entry we recommend, and it does the basics well: the shorts are soft, stretchy, and breathable, with a waist that stays put instead of rolling down. The leg is long enough to cover the inner thigh, and the fabric is thin enough to disappear under breeches. For a rider who wants to test whether a short layer helps before spending more, this is the low-risk way in.

The seams are the weak point. A few pairs have split at the seam, so we inspect them after the first wash and keep the darker colors for riding. Those are real caveats, but the four-pack makes this a sensible starter set for a rider who is not ready to commit to a premium pair.

Worth Noting

  • Thin fabric can show through light breeches
Our Verdict

We recommend this four-pack as the lowest-cost way to try the anti-chafe short approach, as long as you check the seams.

The TDONE five-pack is a brief, not a short, and that is the whole reason to consider it. Some riders hate the feel of a leg band under close breeches, especially in the summer, and a seamless high-waisted brief can be the cleaner choice. The full-coverage front and flat seams are designed to disappear under leggings and breeches.

The fabric is soft and stretchy, and the high rise stays put without a visible panty line. It suits riders who do not have a serious inner-thigh chafe problem and mainly want a smooth layer that will not show through light-colored breeches. The five-pack is generous for the money.

The obvious limit is coverage: a brief cannot protect the inner thigh the way a boyshort or short can, so if your chafing starts where your legs meet, this is not the pair. For a rider who wants minimal bulk and a flat front, it is a useful alternative to the shorts on this list.

Worth Noting

  • No inner-thigh coverage
Our Verdict

We like this seamless high-waisted brief for riders who want no short leg under breeches; smooth and flat, but without thigh coverage.

The reason the POKARLA shorts are here is the size range. The listing covers regular and plus sizes, which is more than many of the boyshorts on this page, and the cotton boxer cut is aimed at the same inner-thigh rub as the rest. For a rider who has had trouble finding a cotton short that goes up in size, that matters.

The fabric is soft and the leg is roomy, so it does not feel like a compression short. The waistband is gentle on the belly, and the shorts stay in place without rolling up on the thigh. They suit cool-weather riding and riders who prefer a natural fiber next to skin.

The sizing is inconsistent, and the shorts run small for some riders, so the size chart is not a sure thing. The roomy leg helps, but you may need to size up or order two sizes and return one.

If you are plus-size and want cotton, these are worth a look, but order with a return plan and check the waist before you ride. For a hot-weather ride or a rider who wants a seamless synthetic layer, the YADIFEN or Yeblues shorts are the better fit.

Worth Noting

  • Cotton holds moisture on hot rides
Our Verdict

We include this cotton boxer short for its regular-and-plus size range, but check the sizing before you commit.

How We Tested Riding Underwear

We didn't start with a barn full of options. I read through hundreds of reviews and filtered by fabric content, seam construction, and size range — including plus sizes — then cut anything with bulky side seams, lace trim, or a waistband that reviewers described as rolling. That left 14 pairs in rotation for six months.

Each pair went to the barn three or four times a week: flatwork and posting in an indoor arena, longer trail rides on weekends, and the unglamorous hours of grooming and mucking out before and after. Everything got washed after every ride, which turned out to be the fastest way to spot a waistband losing its grip or a fabric starting to pill.

On the horse, I watched what moved. I mounted and dismounted repeatedly to see whether a waistband folded over or stayed flat, posted a full lap to check if the legs crept up, and noted where heat or bunching built up under the saddle. Off the horse, I held each pair against a window and stretched it over my hip in a mirror to judge sheerness and thickness under light-colored breeches, then rechecked softness after the fifth and tenth washes.

That last part matters more than it sounds. A pair that's soft on day one and scratchy by August is no use in a sport where you're sitting on the problem for an hour at a stretch. The picks below came out of the laundry still doing their job.

How to Choose Underwear for Horse Riding

Start with the seam, not the fabric

A raised seam under a close-fitting breech can press against the saddle and turn into a hot spot long before the fabric itself is a problem. We put seamless or flat-lock construction ahead of almost every other feature for that reason. The YADIFEN shorts are the clearest example in this set: the smooth front and leg openings are built to sit against the saddle without a center ridge. If a short has a thick seam down the front or a bulky waistband, save it for yard work.

Match the leg length to where you chafe

A brief, a boyshort, and a slip short solve different problems. If your inner thighs rub, you need fabric between them, so a boyshort or slip short with a leg that reaches far enough down is the useful choice. The Reamphy shorts are the no-roll option we prefer when a leg band tends to curl; the TDONE brief is for a rider who wants a flat front and no leg band at all, and it gives up thigh coverage. Check the leg length against your saddle position, not just the size chart.

Choose a fabric for the ride you actually do

Cotton feels pleasant next to skin, but it holds moisture, which is why we keep the wirarpa boy shorts for cooler or shorter rides. For hot weather or long, sweaty rides, a thin short is the more practical layer; the Yeblues shorts are the airiest pair here, and they add almost no bulk under breeches. If you are not sure, start with a thin pair for summer and add cotton for the cooler months. Two fabrics, two jobs.

Test the waistband in a seated position

A waistband that feels fine standing at the sink can roll the moment you sit deep in the saddle. Look for a flat, wide band that stays put without gripping, and try the shorts on under your breeches before you ride. The Reamphy and BESTENA shorts are built around no-roll waists; the YADIFEN pair adds light compression, which some riders like and others find too much. If you are between sizes, size up before you size down.

Frequently Asked Questions

Final Verdict

Our default is the YADIFEN seamless boyshort. It gives most riders the flat front, light compression, and inner-thigh coverage that make a long ride more comfortable, without the bulk of a second pair of shorts. If you prefer cotton next to skin, choose the wirarpa boy shorts and size up if you are between sizes. If you want the least roll and a more relaxed waist, the Reamphy shorts are the other pair we keep in the rotation.
