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. 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!

Piper Fusion Breech by SmartPak - Full Seat is rated 4.0 out of 5 by 27.
Rated 5 out of 5 by from Highly recommend! I’ve had a pair for about two years now and they are my absolute favorite breech (long time knits lover). Sticky tight with belt loops. The only thing I didn’t like about the old version is the silicone around the waist band but the new pair didn’t have that. Comfortable and flattering.

Rated 5 out of 5 by from So grippy! Seriously love these pants! When I first got on with them I felt so secure and stuck into the saddle! The design is flattering and attractive. The fabric is great, repels water and the still looked clean after grooming, riding, and bathing 2 horses in the summer heat. They are definitely more breech-like than tight-like though, I wouldn't say they are cooling but not as hot as some breeches. Liked them so much I ordered another pair in a different color.

Rated 1 out of 5 by from Yuck When the box arrived it had been sitting in the sun for a little while. I opened the box and it smelled like a chemical factory.

Rated 4 out of 5 by from COOLING! I bought my first pair of these about a month ago and just bought another pair. I am IN LOVE. I’m a plus sized rider who has chronic illnesses and I’m always trying to find actual breeches i like. Pipers never fit me right, they always get sticky to my skin to where I can’t use the restroom if I’m at all sweaty. And part of my illness is sweating. A breeze across them after sweating or rinsing a horse and getting wet is FREEZING. They truly are cooling and clean so well. My one peeve is the waist height. I wish they had a bit more of a rise in the front to avoid the dreaded camel toe. I also wish they were a bit thicker in the waist. A smoothing panel on the front with a higher waist in the front would give these a solid 5 stars. But other than that, I wish I could do a 4.5 because I truly do LOVE these breeches and really hope for more colors.

Rated 2 out of 5 by from Updated version not as good I bought these for the first time in May 2021, just as I was losing weight from having a baby. I unexpectedly loved them and wear the three pairs I got from then almost relgiiously. Fast forward a year, I'm now the same weight I was before the baby but my hips are permanently wider. I bought another couple of pairs and was super unhappy to see they were updated with a new fabric type that was much less stretchy. Not only was the less stretchy fabric less comfortable and hotter, it was now super difficult to get these over my hips. Super disappointed that the new fabric isn't stretchy anymore. Bring back the old design!

Rated 5 out of 5 by from Best tight/breech ever! Comfortable, perfect rise, great fabric and just the right amount of grip. I swear they make me look slimmer! :-)

Rated 5 out of 5 by from Great fit and sticky seat Finally a pair of breeches that fit me. Have gotten lots of compliments on the (green) color also.

Rated 5 out of 5 by from My favorite Smartpak breech! I’ve ridden in these breaches a few times and each time I love them a little more. The the fit is amazing! Being tight-like I worried they’d slide down, but the belt loops allow for a belt to keep them in place. The silicone seat grips well, the pockets are perfect for holding treats or a phone, and the fabric repels dirt and hair. Each time I wear them I get many compliments.

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!
