      Mountain Horse Polar Breech is rated 4.4762 out of 5 by 63.
      Rated 4 out of 5 by from Good riding pants Bought these for my wife but found they fit me much better. She's 5'8" , I'm 6'1". She's disappointed but, I'm happy. They are a comfortable, non bulky , quieter alternative to other winter over-pants.

      Rated 3 out of 5 by from Can't trust size chart! As far as keeping you warm there great but finding the size that fits is another story. They are unisex which I don't like to start with since men and women aren't built the same. I bought an xs pair for a friend who wears a jean size of 4 to 6 and they wouldn't go over her hips, they were listed for a 29" waist so they should have fit and she should have had room for jeans underneath. This is a tall and slender woman. She ended up getting the medium that I had ordered for me. I wear a size 8 to 10 and the medium was to small in the waist which going by the waist chart I should have been more than good just like she should have been. Were both somewhat tall, she is 5' 8" and I am 5' 7". I am now waiting to get a larger and see if they fit. Here's hoping they work since they are correct about keeping you warm on those bitter cold days

      Rated 5 out of 5 by from they are warm! these are great outdoor pants, many good features. the one thing I would be careful of is the sizing, they seem to run small around the waist. you can adjust them to an extent but I would either go up a size or talk to someone in customer service to make sure you get what you need. once I got ones that fit, I couldn't be happier.

      Rated 4 out of 5 by from Ready for winter! I recently bought a pair of a Mountain Horse Polar breeches in time to test them out on very chilly day. I would normally have ordered a medium, but based on reviews I ordered the small. I am 5' 6" and 132lbs and they fit well. I would have room to add another thermal layer, but not enough room for jeans. I love the articulated knees and the versatile zippers...very handy! I only have one complaint. On a 4 hour trail ride I had trouble with the seam intersection of the quilted lining...painful! I cannot imagine why there is not a gussetted crotch. Is it because they are unisex and men don't have this problem? Fortunately I sew and I am planning to redesign that area. If successful the polar breeches will be perfect! They are otherwise beautifully designed and so well thought out.

      Rated 5 out of 5 by from Why didn't I buy these sooner????!!! Safe to say that these have changed my barn life this winter. Mountain Horse's designers are geniuses. These pants keep me so warm and the full seat enables me to ride and feel comfortable in the coldest temperatures. Great gators to keep the snow out. Zippers where you never thought you even needed zippers (but they're so useful!), water repellant material, well-placed pockets…. I could go on. I am 5'6", 115 lbs and 26" waist and got the XS. They JUST fit -- but fit me perfectly. Together with my Mountain Horse Nordic Light boots and my 8-year-old Mountain Horse jacket, I am warm and happy!

      Rated 5 out of 5 by from These are great! These pants are perfect in the cold weather we've been having. They keep me warm in below zero temps. I ordered a small and they fit well and are comfortable for riding. A little long for me but most things usually are as I'm 5'1". They are holding up well and after a wash they look like new! I am very impressed with the quality and fit and in my opinion are good value for the price.

      Rated 5 out of 5 by from Comfortable and warm! These are stylish and very warm - it was in the single digits today and they kept out the cold and wind. Comfortable to ride in and I like the zippers and extra snaps at the waist. Great Mountain Horse quality! Find these and get will not be disappointed.

      Rated 3 out of 5 by from Sizing is difficult Well, I did not see that these were unisex sizing until after purchasing. Nonetheless, I used the sizing chart and ordered a size L. I am 5'11" and about 185lbs. I wear a size 12/14 in street clothes. The L fit great everywhere except the hips, which were quite tight, and waist, which was simultaneously tight, but gapping at the elastic part in the back. Very odd. I decided to order a size XL for comparison. The XL arrived last night and I don't even need to unbutton/unzip them. They are so large, I can just pull them on like sweatpants. Baggy all over. For some reason, the size L has a 2 button waist adjustment on either side (you could take the waist in by 2" if needed by moving the snap), but the XL does not have this same feature. Very odd. I sent the XL back and will keep the L and... hope to become slightly smaller in my hips??? I'm still thinking that one over. Other than sizing, these seem AWESOME, which is why I am really torn on what to do with the size L pair - keep or return? They are so toasty warm, super easy to get on and off thanks to the full length leg zips on either side, and the full seat gives lots of grip. They would be super duper awesome if they were simply cut for a woman instead of unisex.

      Rated 4 out of 5 by from Warm, comfortable and nice for riding In very cold weather these are my go to riding pants.   Very comfortable and well made.  Not flattering however.   The hips are very oversized.  I'm 5' 8" 150 lbs and have the medium size.  They are just long enough and fit my 31" waist with little room to spare.  However the hip area must be at least 36" -- it's overly wide/roomy.

      Rated 5 out of 5 by from I stayed warm! Wanted riding pants to wear in the winter without bulk, to stay warm and dry.  Wore them on Christmas Eve and the temperatures were low 20's.   Product is excellent.  Wore them with a nice pair of thermal long johns.  Unisex sizing but would like female sizing options.

      Rated 4 out of 5 by from Extremely Warm! I got these pants just after our 10 degree days turned to the forties. They will make great pants for bitter days. They are what they look like in the ad, somewhat bulky, fitted at the waist. Sizing was difficult for me. I am keeping the extra smalls though they are shorter and tighter in the waist than I would like. The smalls were way too loose in the leg.I am 5ft 6 and 108 lbs. I were size 26 reg. breeches.

      Rated 5 out of 5 by from Excellent Purchase These winter breeches are great and live up to the positive reviews. They do run bigger just as the reviews say, but I ordered a size down and extremely satisfied. Usually I wear a size small (3/4-5/6) and I ordered an extra small in these and they fit perfectly! I wear them comfortably over jeans, but can easily get on from the ground when I wear regular breeches underneath them. These are great.

      Rated 3 out of 5 by from Unisex cut; not for curvy women I've owned a pair of these breeches that I bought from another vendor and asolutely love them. Friends from my barn have warned me that the same breech from Smark Pak are oddly cut (male cut; straight through hips), but I had to try after my other pair wore out. I returned them because they were definitely different (small) through the hips and thighs than the ones I have had before. Be forewarned that these appear to be unisex size and not for curvy women. Very sad about that because other than that, these are great winter protection. Very warm and waterproof!

      Rated 5 out of 5 by from Warm and not bulky! I just moved to an area with cold winters and needed something warm to ride in. I just used them for the first time today at 24 degrees and a 15 mph wind (so with wind chill it was about 7 or 8 degrees) and they are excellent at keeping the wind out and I was comfortably warm the whole day. The zippers were easy to manage and I'm sure I'll be using the snow gaiters inside soon. I've used ski pants in the past but they were too slick on the seat to ride properly; these are actual breeches, so the seat has some grip- nice and easy to ride in. Although they kept me warm, they're not at all bulky or bunchy, which is another improvement over ski pants or jeans with long johns. I have no idea how durable they will be, but the materials and construction are quite good and I think they'll last for quite a while. Am planning on giving a pair to a friend in Montana for Christmas, they're that nice.

      Rated 5 out of 5 by from Very warn and easy to wear. These are really nice pants and very high quality. They are easy to get on and off and have GREAT zippers. I like to put them on over my breeches in the morning and when it warms up in the afternoon I take them off. I'm going to use them for skiing too. They are very comfortable.

      Rated 5 out of 5 by from warm in upstate NY Held off because of the price but so happy I ordered these breeches - they are so worth it.I am at a cold barn in upstate NY every day and am able to ride in a icy indoor or out on trail in comfort. Higher -waisted than I expected since everything seems to be low waisted these days but warm and cozy. Wear silk long underwear underneath and I am fine. Nice quality. Good length with zipper to accomodate boots.

      Rated 5 out of 5 by from Perfect Cold Weather Gear! These pants are fantastic! The fabric is very nice and WORKS in cold, dirty, working conditions. They are comfortable and fit well. They are not hipster style clothing which I appreciate. (I don't have to tug on them to keep my body covered!) I can wear them over other layers too. The fasteners work well and they open at the ankles to accomodate boots and stuff. I think they may double as an extra pair of ski pants too when I hit the slopes.

      Rated 5 out of 5 by from Changes the game These full-seat breeches totally changed my relationship to winter riding. They are extremely warm and comfortable, totally waterproof, and sealed well (no drafts at the ankle). As other reviewers have said, they are sized generously enough to layer (today, I wore jeans under them). Best investment I've made this winter!

      Rated 3 out of 5 by from "Mountain Man" breech These breeches are made the best. They are warm, materials and stiching are excellent and I especially like the seams at the knees for easy bending. Problem is they are unisex in size and I would say they are actually made more for a man than a woman. If you happen to be shaped like a man and are really tall and order a smaller size you might get along pretty well. If you are shaped like a woman and don't mind a big gap in the waste and an extra 6 inches at the bottom of the pants, you will also probably get along well with these breeches. For what they charge I think it is time Mountain Horse ditched the unisex sizing and designed something specifically for a woman's figure and height. That said, the workmanship is great and although pricey, you get what you pay for. Too bad they don't fit!

      Rated 5 out of 5 by from Super Warm LOVE these pants. It was 7 degrees here today. I stayed toasty warm all day. I have stopped wearing my Carhartts because these pants are warmer. They are comfortable to ride in and breathable so I do not over heat.

      Rated 5 out of 5 by from awesome quality Nice pants w/ lots of extras. These pants look so durable. I haven't gotten to use them much yet but, they look like the perfect pants to put over my riding pants in the extremely cold winter weather in SD.

      Rated 5 out of 5 by from Great quality, but very large I'm 5'5 and 105 pounds (and normally wear 25 inch waist / 30-32 inch length jeans) ... and I tried these in the smallest size, XS. Unfortunately, they were way too big!The quality seems great, and I would definitely buy if they had only had a smaller size...

      Rated 5 out of 5 by from Very Warm! I got these pants over Christmas. I have been wanting a pair since 2011. I love them they are very warm!!!! I even can wear them with my jeans, but you get very warm. I would wear them with breeches or sweats. :) But they look great and hold up!

      Rated 5 out of 5 by from Great pants I love mountain horse products and these pants aren't an exception! I live in Utah and we have cold, snowy winters. I board my horse at a facility that keeps all the horses outside 24/7 in paddocks and shelter. They don't have a barn and other than the shelter there's no cover for me from the snow while I'm working with my horse. So far these pants are indeed waterproof and wind proof. I work my horse in the outdoor ring year round the outdoor round pens and these pants keep me warm and dry. In fact, I just got back from the barn and it's snowing hard right now. I was outside till almost midnight cleaning my horses paddock and shelter, etc. It was a whopping 28 degree and I was toasty as ever!

      Rated 4 out of 5 by from Runs Long! Many reviews say that these breeches run large. I am a size 16, 5'7" and they fit loosely, but they are looong!Giving 4 stars across the board based on previous MH products but will have to exchange these for a smaller size.
