Reviews
Horze Grand Prix Thermo Silicone Full Seat Breeches is rated 4.2 out of 5 by 21.
Rated 4 out of 5 by from Favorite winter breeches I haven’t found a perfect pair of winter breeches, but these are the best I’ve found. Love the high waist. No strangely placed seams. Super warm & cozy fleece inside with great wind protection on outside. After reading reviews, I ordered 28R (I’m normally 30R in Romfh), which was the correct size. They fit looser than my normal weather breeches, but nothing baggy. They aren’t cut “curvy”, which is unfortunate in my case. But I also don’t know what the hubbub is about the calf sizing. I don’t have skinny calves or weightlifter calves, and on me these seemed perfectly normal. I only wish these companies would realize that WE NEED PETITE OPTIONS!!! These are pretty long on me (I’m 5’4”), but nothing abnormal.

Rated 2 out of 5 by from Poor fit below the knee I wanted another pair of fleece lined breeches for hunting and they are hard to find in tan. I ordered these but sent them back. They fit true to size but below the knee/calf portion is huge. It was like having sweat pants on. There was no way that was going to fit comfortably under boots.

Rated 5 out of 5 by from Great Fft! So comfortable! These are my third pair and my favorite winter breeches by far. So warm, comfortable, perfect amount of grip, repel dirt and hay, and they look GREAT! Keep me warm on trail rides or in the arena. I'm long waisted, just under 5'5", 120 lbs., with a short inseam so all breeches are 'long' on me, so I wouldn't say these run 'long'.

Rated 4 out of 5 by from Comfy for winter, well made I bought the green. The color was much lighter than I had hoped and thought it would be based on the website photos. Item was on backorder and by the time I received it, it had gone on sale on various sites.

Rated 5 out of 5 by from Super warm and well made! I have been looking for warm breeches to add to my winter riding wardrobe. These breeches are super soft with their thick fleece interior and soft shell exterior. These are a bit snug to get on but are easy to ride in. So far I have been extremely happy with this investment.

Rated 5 out of 5 by from Nice quality and great for weight lifter calves I like the quality of these breeches, and they feel like they will be warmer than anything I own for winter. I am looking forward to testing them out in cold weather. I see that many reviews complain about the baggy calves. For me, they are a benefit. I have muscular calves and have a really, really hard time finding anything that will fit my legs that are not comically big at the waist. These fit my thighs and have room to spare for my calves. I will have to take in the waist slightly, but that is just a matter of adjusting the clasps, which is a lot easier than suffering zero circulation in my calves.

Rated 5 out of 5 by from Purchased for my wife. She loves the fit and warmth they provide.

Rated 2 out of 5 by from I bought the Horze brand before and LOVE the way they fit and wear. I read the reviews on the thermos Horze and there were a few comments that they run big and the calves are baggy....they were spot on. I wish I ordered a size smaller, they don't have anymore:( The non thermal ones run fine. These are very warm and like one of the other customers say...the baggie calves are in my boot anyway and they don't interfere with my riding...next year I will buy the next size smaller for sure. I have a few winter breeches and they are very fitting where the horze is more comfortable to wear...the fabric is the best!

Rated 4 out of 5 by from Winter Breeches I like them for the fit above the knee, but below they are loose and hard to/impossible to get into boots. I wish Velcro at the ankles would come back. It is nice to be able to tighten the bottom of your breeches.

Rated 4 out of 5 by from Warm and comfy So far so good. Does run large. Fits like a full rise. Some stretch. Appreciate the Pockets and the bottoms. At 5’9 with longer legs these work just great.
