    Ariat Tri-Factor Full Seat Breech is rated 4.2 out of 5 by 25.
    Rated 4 out of 5 by from Flattering, comfortable, don't get the white So I would give these a 5 star in every category but stain removal. I bought the white and expected them to be a little harder to keep clean but I have some milder stains that just won't come out after the first wear. Even after spot cleaning and soaking. I've tried everything.

    Rated 4 out of 5 by from Curvy fit I have a small waist and full hips and these don’t gape at my waist or fit to snug in my hips. I usually ware a 28-26R and I had to go down to a 24R. Tons of compliments on these pants at the show. They are not stain resistant!

    Rated 5 out of 5 by from Love them! I bought these because the I was looking for another pair of silicone grip breeches. Usually I buy the Piper silicone breeches but wanted to give these a try since smartpak has changed their silicone breeches. First of all these run small, I had to go up a size and the legs a tiny bit short(I’m 5’5 and 130lbs ordered size 28)But the fabric is so breathable and cooling in hot weather. And most importantly to me the silicone grip seat is perfect! Not too grippy but just right. They are higher waisted then Pipers with more of a compression fit. Wish they came in more colors.

    Rated 1 out of 5 by from Returned and not getting another I bought this breech extremely excited. I'm used to buying Ariat tights or leggings not their actual breeches. I'm a L in their leggings and tights, normally a 32 in jeans and other breeches I have. These pants didn't even go over my bum. Being an equestrian I have a lot of leg and butt muscle. These breeches were tight along my inner and outer thigh, my calves, and my bum. When I finally wiggled them up to my hips, it was NO WHERE near a 32. Safe to say they were not true to size at all for me, would not recommend to thicker, muscley barn women.

    Rated 5 out of 5 by from My favourite breeches! I have these in every colour now, fit like a glove, incredibly comfy, can’t recommend enough. I am a size 8/24 and always struggle to get legs to fit me nicely without being baggy around the knees, these are spot on. Perfect. Please bring out another colour! :-)

    Rated 5 out of 5 by from New favorite breeches There is nothing I don't like about these breeches. They're flattering even on my ample self, super comfortable, and the fabric stays looking new wash after wash. The type of silicone they use on the full seat is grippy but not too grippy and it lasts, unlike other brands. They have a super premium look so they are my go-to for clinic rides. Even though they are IceFil and therefore summer breeches, I put a thin baselayer under them and wear them happily in the frozen Northeast. My only wish is for more colors: gray (so sad they exist in knee patch but not full seat!), burgundy, or dark green would all be great.

    Rated 3 out of 5 by from Beware: mine ripped Purchased the Ariat Pro about 11 months ago. I’ve schooled in them once a week since then and hand washed them after each session. Love the grip, love the fit and the fabric weight is perfect for hot SC summers. However, after riding in unusually cold weather this weekend, my pants had 2 smallish holes on the inside knee. I dismounted cleanly, it wasn’t a particularly grueling work out (just some trotting and low cavalettis), but I noticed the holes right after dismounting. It's as if the grip got stuck to the saddle. They’re such beautiful pants, but I’m bummed that after less than a year they seem to have failed. I’m leery of buying another pair.

    Rated 1 out of 5 by from Run small in waist but loose on legs Not sure what body type these breeches work for but not mine! I usually wear Romfh, for comparison sake. Waist was super tiny but the breeches fit fine everywhere else. Also, there's a big 'ARIAT' advertisement down the left leg that isn't shown in the pics.

    Rated 5 out of 5 by from Love these! I’ve only worn these to one show so far, but they’re awesome! The full seat is so much better than my old knee patch breeches. Love the pockets! Nice style too so they look really good in the show pen!
    Date published: 2019-10-07
    Rated 5 out of 5 by from Great features and fit! These are my favorite breeches and I’ve actually bought them in navy and black. They got me great! I have curves and struggle with breeches being way too big in the waist when they fit my hips and thighs. I’m not heavy however so I’m not suggesting these wouldn’t fit a smaller person. The material is a little slick so they stay clean and wipe off, allowing a couple of wears if I don’t get too dirty. The full seat is grippy so they aren’t slick in the saddle. Love them!
