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 - Knee Patch 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 knee patches 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 - Knee Patch is rated 4.4 out of 5 by 25.
Rated 5 out of 5 by from GREAT PANTS PLEASE BUY THEM FOR YOURSELF TRUST ME! I have never owned a better breech in my life! First of all the ribbed texture on the butt in unique and fun! They serve as a riding tight with belt loops( which I always need!) but they can pull off a more traditional look with the buttons and the belt loops. Perfect for summer with mesh part around ankle. The colors are all the ones you want and more! These helped me survive summer. They are so comfortable and somehow I just do not sweat when I am wearing them. I got them in grey size small.

Rated 5 out of 5 by from Great tights! I just bought 2 pair of these and now I want more! Comfy and flattering.

Rated 3 out of 5 by from I wanted to love these These look great and have awesome details. There were a lot of things I loved about them like the material, phone pockets, faux zipper and buttons, and mesh sock bottom. However there were two things I couldn’t get past and so I ended up returning them; the rise and the crotch seams. The seam that goes from the fake fly to your butt was short, so the seam was up my butt so far that it felt (and looked) like I had a wedgie that wouldn’t go away. And they were not high waist enough for my liking. I would’ve like them an inch higher. I debated for a while about returning them and ultimately decided to.

Rated 5 out of 5 by from Most Comfortable Breeches! I was looking for a new comfortable breech for the summer and this one definitely checked the boxes! The fabric is incredibly comfortable with great four-way stretch. After riding in them for close to 6 months now they have still held their shape and structure great. I was skeptical at first of the lack of zipper/ button on the front, but they pulled on easily. The waist banned is lined with a small amount of silicone which truly does wonders in terms of helping them stay up throughout my entire ride. I also appreciate the wide belt loops that easily fit my favorite 2” leather belt. The mesh pockets on the side are great for cell phone storage, especially when riding alone. They fit very true to size for me. I normally wear a size 4/ 26R and ordered a small. Lastly for care I machine wash on cold and hang dry and they have held up great!

Rated 5 out of 5 by from Great pair of tights Perfect for schooling shows, repels horse hair and the tights have pockets and belt loops making them a bit classier. Fit very well and stayed up even without a belt! Will be buying more.

Rated 1 out of 5 by from No!!! They changed a great thing I ordered these when they first came out and loved them - wanted one in every color. But they have changed the design when they added colors and this hybrid breech is a huge disappointment now. The waist does not have the silicone grip as before and fits larger around . I ordered same size and with this new waist I would need a belt to hold up - and I do not have a small waist. I am 5’9” I fluctuate between ladies size 12 and 14 ordered XL both times Smartpak please go back to Origional design

Rated 2 out of 5 by from Baggy thighs! Bought at a discount, tried them on, and back they went! Nice gray color but the fabric has stiff and the thighs were baggy! What was that about?! I usually take a small or medium, tried the medium, the length was good, as was the waist. 0h well, try again!

Rated 5 out of 5 by from Make more colors! I love these fusion breeches so much - they feel more like breeches than a legging. TBH I am not the biggest fan of leggings because most of them don't have enough hold and are too slippery. I really wanted a light pair of breeches with pockets that can hold my phone so I can go on trail rides in the summer, and these are perfect. The waist band is a little tight and I need to put some effort in pulling through past my hips, but once they're on, they're so comfortable and fit just right - not too tight, not too loose. The material seems to repel dust/dirt very well and the silicone knee patch is a nice feat. I highly recommend these to anyone who want a light breech but don't feel totally comfortable with riding tights/leggings. They really are a fusion! SmartPak - please make more colors!!! For reference, I wear a size 26 in RJ classics, Pipers, and Dover brand breeches. I am a 28 in Ariat, Tredstep, and Tailored Sportsman. I'm about 5'4" and weigh about 125lbs and the size small fits me well (again, the waistband was tight only when pulling them on).

Rated 5 out of 5 by from Looser Fit with More Structure I am a big supporter of the knit and tight pipers. These are a heavier fabric than the tights, with a roomier feel through the leg, but fits true to size in the waist. I like the mid-rise fit. The fabric is thicker so may be a bit much for the heat of summer. The pocket is massive and in the exact right spot. I like the belt area being so wide to stop it folding over, and while I'm a solid 18/20 I probably could have gone down to an XL.
Date published: 2022-05-18
Rated 3 out of 5 by from Nice, secure pockets Fit around the mid-section was good, but a bit loose in the legs. The material is warmer than I expected. Doesn't feel breathable to me, but is a good weather transition breech.
