Excellent arctic breeches, NOT just for riding!
I bought these for winter riding. They're excellent! Well made and high quality!
Water proof, wind proof and seriously warm even in the coldest conditions. The seat is reinforced and sticks well to my (synthetic English) saddle. They have generous zippers all the way up the legs, reflective stripes, large pockets and double ankle protection to tuck into your boots and over the boots with a flexible strap. The sizes DO run generous, so don't bother upsizing one size. Even with several layers underneath and bulky winter boots, they are generously cut. You can move in them freely and comfortably.

Since I've purchased them, they haven't only served me well through the winter at the barn, but I also took them for a week of winter camping in Iceland (howling winds? No problem at all!) and a week of snowboarding in the Canadian Rockies during polar vortex conditions. -25* cold? No problem, throw a couple of layers under them. Toasty. Sliding down the side of a snowy mountain on your butt for several days? (I'm not an excellent snowboarder anymore.) No problem. Warm, dry, and no noticeable wear to the seat even after some serious abuse that's well outside of the intended use.

Would absolutely buy these again in a heart beat, if they ever got damaged. But sturdy as they are? It'll be a while before they'll need replaced. Would recommend them to anyone who lives in cold weather conditions. Well worth the price.

great winter riding pants
I am only 5'2 and due to my love of food need a of course they are too long, but I am having them shortened by a professional. I am anxious to wear them as they were very warm and comfortable when I tried them on...Nothing better than winter pesky flies and you can see forever without the foliage. Makes familiar trail totally new.....

Product fulfills description
The pants are warm and perform as advertised. I am 5'6" and weigh 200 pounds. I wear a size 18 pant which fits a little loosely. I expected these to be a bit tight fitting and they are around the waist and thighs. I wish they made a 1x. The versatility of the pants is impressive from the elastic stirrups to the zipper down the pantlegs.

Keeps me warm.
These polar breeches are great! I put a pair of insulated underwear underneath and was very comfortable. I did not get cold at all. They are the best purchase for winter riding. I love the zippered sides. It makes it much easier to put my winter riding boots on.

Returned due to small size
I ordered an XL. It was marked XL when it arrived. My daughter takes a medium and it was okay on her. I couldn't get into it and sent it back.

Okay, where have these been all my life? I never would have believed how warm I could be all winter until I started using these overpants. I got them a little big on purpose. I wear them over long underwear or plain breeches when it's pretty cold, and when it's super cold I add fleecy sweatpants. I'm outside all day and it's astounding the difference these pants make both in the saddle or for farm chores. If you can't keep warm, get yourself a pair!!!

Terrific warmth
I have a pair of these riding pants that I have worn for two years now. I just wear a pair of under armor long johns under them and I am good to go for the day. They are easily washed and hung for over night drying.

I love these pants! I received them for a Christmas present and have been using them everyday since I got them. The temps have ranged from 20 to 40. I have worn them w/just long johns and they have kept me warm. I wear a size 14 jean and I am 5'10" and the large fit me perfect. They really have a great grip in the saddle! LOVE THEM!!!!

I bought these pants last year and just now got to test them out in the Texas winter weather...they are WONDERFUL!!! I am always cold, no matter how many layers but with these pants I am warm and toasty! They're very comfortable, breathable and great!

on behalf of someone else.
there's agirl at my barn who uses these, she loves them and says their warm enough to ride up here (at -20 and lower temps) so if you're looking for a cold weather pant I would say look at these.

I chose the Mountain Horse Polar breeches because we ride in the frigid Northern Minnesota winters, and a friend loves her polar breeches.

Hi, looking at these pants and not sure what size I should go with. I wear a size 9/10 in pants?
A shopper on Sep 29, 2014

Is the waist adjustable, maybe with elastic or extension tabs?
Betty N on Oct 11, 2015
BEST ANSWER: There are side tabs to cinch. I am generally a medium. The pants that first arrived were XL bc the site defaults to this and every time I left the site a couple of times to look something up and the size reverted- so just double check the size you want when you actually order. The delay in getting the correct size (especially since I finally ended up with a small) meant that I never got to wear them last winter. I hope they're great!
does this breech have a full, gripping, seat?
A shopper on Oct 27, 2017
BEST ANSWER: it is full suede like seat. I guess it is gripping.
True to size?
A shopper on Nov 9, 2017
BEST ANSWER: They are unisex sizing, so for most women they will run a bit large. It can depend on how you're built.
Hi I bought a pair of mountain horse pants 2 years ago and they say W,P.S. Comfort on the bottom of the leg and I was wondering if these are the same ones as the ones I bought here before? I want to get another pair that are the same ones same size cause they have been awesome to wear in the winter stay nice and warm and dry

Is 35" the only inseam you have in a large? Because that is 6" longer than my inseam
A shopper on Nov 16, 2014
BEST ANSWER: The inseam measurement on the large is 34. Unfortunately that inseam measurement is the only length that comes with the large.
What size would you suggest for a man who wears a 36"waist x 30" inseam?
