Why We Love This

Designed for those who want the comfort of a tight but like the look of a performance breech, the Piper Fusion Breech - Full Seat blends the best of both worlds. Technical stretch performance fabric allows you full range of motion for ultimate comfort, mesh sock bottoms maximize breathability, and dual mesh pockets let you securely store your phone. They have the aesthetic of breeches with two faux buttons, faux fly front, and wide 2.5” waistband that lets you accessorize with your favorite belts. A silicone-enhanced waistband helps keep your shirt tucked in and the breeches securely in place. In a fun, crosshatch diamond plate pattern, the silicone full seat give you extra grip in the saddle. A rear pleated panel below the waistband not only lends itself to a unique touch, but also offers a flattering design so you can look and feel your best! 

Due to the anti-slip silicone design inside the waistband, we recommend ordering your normal size for a supportive fit or a size up if you prefer a roomier fit through the hips and waist.

Rated 5 out of 5 by from Love these! These are genius! Durable substantial smooth fabric that doesn’t easily show dirt, fits perfectly over my curves, and the silicone is fantastic. Really grips the saddle and I think it’s helped me not slip around too much as I’m riding a young horse who like to surprise me with occasional scoots and spins. These are my new favorite so please add more colors!

Rated 5 out of 5 by from Comfort, style and function I love the fit, comfort and style of these breeches. I receive compliments every time I wear them followed by, "Where did you get those?" The full seat adds just enough grip and the waistband smooths. I love the faux zipper front because I hate the bulk and discomfort of real zippers. I find them to be true 3 season breeches. I've bought both colors and wish they made more.

Rated 5 out of 5 by from Love these! These are now my favorite breeches and I cannot wait for them to restock! Super comfortable, just the right amount of grip, lightweight. I am 5’ 10” about 135. I typically wear size 26L and size small fit and is long enough!

Rated 5 out of 5 by from great Quality I loved the look and the feel of these breeches. They seem of such good quality. Unfortunately the size I ordered was too small with no larger sizes I had to send them back.

Rated 3 out of 5 by from Nice fabric, tight fit I was hoping this would be a warm weather breech that I could love. I wanted the ease of a pull-on tight and fabric that is as supportive and shaping as a breach without the sweat factor. And, generally, I liked the light weight of the fabric. Unfortunately, as others have noted, the waist band is VERY inflexible. I struggled mightily to get the breaches over my mature woman hips and bum and worried that I wouldn't be able to get them back off. (Again, a struggle, but I did get them off.) These might be good for a thin, young rider but for those of us with a womanly figure, they are a no go.

Rated 4 out of 5 by from Comfortable but.... I wore mine for the first time yesterday. I was extremely worried as I put them on...I struggled to get them on over my hips (I’m a tad curvy) because there isn’t much stretch in the waist. Once I got them on, they fit like a dream! I found the silicone to be quite sticky. My phone fit great in the pocket as I rode. I wish these came in more colors, then I’d be buying dozens!

Rated 5 out of 5 by from I’ve decided I really like these I’ve had these for awhile, and I have decided that I love them. Wasn’t sure at first—they felt a little plasticky—all the nylon and silicone—and they are. The full seat silicone kind of clacks together when you first put them on. BUT, I’ve ridden in them and done barn chores now for a few months, and they are my new favorites. They do run small. I sized up, per the reviews, and they fit great. They are just right—not too tight, not too loose. The waistband is very comfortable and it stays put with the sticky silicone on the inside. I thought it might chafe my skin, because I do not tuck, but it doesn’t. I am well into my 50s, and I have a curvy bum. I think these are flattering. I haven’t worked up a huge sweat in them yet, but they feel like they will wick very well. The full seat is sticky enough in the saddle for me. I can still post, but there is a nice contact for sitting trot and canter. These are going to be my go-to all summer, I can tell. I have the green. Would buy in a pretty burgundy plum, too (hint, hint).

Rated 5 out of 5 by from LOVE these!! Please, please make in more colors! These are my absolute fave. Lightweight and high quality. But the BEST feature is the silicone inner waistband. No more pulling up my pants when I ride...or any other time. Please make in khaki/tan do I can wear them in shows.

Rated 5 out of 5 by from Love! I bought these almost a month ago and they're my new favorite breeches! They're so comfortable! I wish they had more colors.

Rated 3 out of 5 by from Way too small Bought it, tried it on, returned it right away. I measured myself and bought the appropriate size and putting it on was like trying to get a sausage back in the casing. I might have considered keeping it anyway if it was going to help me stay in the saddle but as other reviewers had noted the seat seemed really slippery.
