    Mountain Horse Polar Breech is rated 4.3 out of 5 by 104.
    Rated 1 out of 5 by from Still waiting for them to arrive Size small came 12/6/17. They were too small. I ordered a small. I am 5'4" and 124 pounds. Sent the breeches back the next day and I am still waiting for the medium breeches to arrive.

    Rated 4 out of 5 by from Very warm! I bought these for riding in the cold PA winters. So far, I'm very happy with how warm they've kept me. I ordered a large, thinking I would wear more layers under them, but really probably could have gotten away with a medium. But they are no so big that it is a problem. They are very long, however. I have to roll them up if I'm just walking in them, otherwise I step on the hems. But in the saddle they are perfect length.

    Rated 3 out of 5 by from Sizing Truly Problematic I read all the reviews about how to get the right size and studied the sizing chart. I measured my waist and hips and ordered the size by what was recommended by the measurement chart. Well the pants were too small. I am 5'4" and weigh 124 pounds. My waist is 35" and my hips are 42" and that measurement was taken loosely over my clothes. According to the charts, that is a small. I normally wear a medium breeches or a size 10. With other breeches underneath, pants would not close. With nothing under the pants, they would close but the pants rise was not high enough and they cut up in the crotch. Ouch. Sent them back and I will try a medium. Hopefully the medium won't be to bulky because I think I will really like them if they fit.

    Rated 5 out of 5 by from Sooooo warm I wore these only once in 35 degree weather and my legs were sweating. They attest to a true winter riding pant. Very comfortable and love how the waist is adjustable and I can zipper these pants on and off in seconds,

    Rated 5 out of 5 by from Mountain Horse Polar Breech I bought these this spring 2017 so have yet to wear them on a nice cold winter day to really test them out. I did try them on and are amazed at how well they fit and felt on. Roomy where they need to be. I'm very excited to try them.

    Rated 5 out of 5 by from Just what I was looking for in cold weather riding pant. I am glad I asked questions before ordering, I got the perfect fit. Thanks

    Rated 1 out of 5 by from Like the 90's Rockies jeans. I haven't wanted these FOREVER. I read the reviews, had mixed feelings about the fit. For reference, I'm at my "winter weight", 130#'s 5'4, wearing a size 4, or a 27 in Cowgirl Tuff Jeans, or a 3/4-5/6 in Wrangler Q baby's. All that being said, I should have fit in an X Small, but I figured out they are cut like the high waisted Rockies jeans from the early 90's. They never worked for me, they'd come up over my first rib. The thigh worked fine and the length worked fine, but Mountain Horse really needs to update with the current cut and style of clothing. Otherwise, they looked incredibly rugged and tough. Disappointed I could not test them on ranch chores.

    Rated 5 out of 5 by from Warmth without bulk. These are the best. Super warm, yet easy to ride, walk and do barn chores in. Not bulky, so you don't walk around looking like the Stay-Puff Marshmallow Man. The rise is high enough that they don't feel as if they are falling down as you walk around. Definitely recommend.

    Rated 4 out of 5 by from Great construction I bought these breeches after a particularly cold weekend. I haven't had a chance to test them out yet because the weather turned milder. I did try them on, and true to the reviews I read before my purchase, they do run large. Fortunately, there are 3 snaps at each side of the waist for adjusting, as well as belt loops. The also run long. I'm 5'5" with an slim/athletic build, evenly proportioned and they're too long for me. I think they'll be fine in the saddle, but on foot I'll have to cuff them. They have an adjustable strap that goes under the boot to keep them from creeping up. I'll review again when I use them riding!

    Rated 5 out of 5 by from Great item, warm I originally ordered this item in a Large as I know I will wear at least 2 layers underneath. However, not only was the Large way too big, it is very long. I returned the item and got the Medium instead which is perfect. I have only used these over pantsonce so as far as durability goes I cannot really say but it seems the quality is good and the value is good. Mountain Horse products are usually really well made.

    Rated 4 out of 5 by from Love these! I love these Mountain Horse Polar Riding breeches! They are so warm and fit over your clothes. Great cuffs and boot straps. They do run a little long but they are the best winter breeches I have found!
    Date published: 2017-01-24
    Rated 3 out of 5 by from Runs small but great product Well made and warm. They run small so I did have to move up a size. I am usually a medium and even given the measurements provided which seemed big, I had to go up a size.

    Rated 1 out of 5 by from Loved these pants but.. I absolutely loved these pants. Contrary to other womens experience the fit was vreat for me. Unfortunately Mountain Horse has a quality control issue which i also experienced with the Stella boots which dont stay waterproofed. These pants only lasted one season before the zippers on the legs failed and wont stay zipped. This is so very disppointing but seems to ne a common issue with Mountain Horse. If not for this failure i would have rated these a 5

    Rated 5 out of 5 by from Warm Got these right before our negative temps and really bad wind chills hit. Really glad I did. I can go out to get my horse without being so frozen that I can't ride by the time I get back to the barn. Just zip them off to ride in the indoor. Would probably keep them on to ride outside, but I'm not really into freezing for no good reason.

    Rated 4 out of 5 by from Warm! The pants are very well made and warm. Tried them on and went outside for a bit on a cold day. Sadly, I have to return them because they are just way too long! At least 6" and as a result, pull down from waist while walking.
    Date published: 2016-12-12
    Rated 2 out of 5 by from Liked the materials used but not the fit These might work if you are tall and have big thighs. Had to return. Knee area was way below my knee and the whole pant was unbelievably baggy. They seemed well made and warm and I liked the feel of the fabrics used.
    Date published: 2016-12-07
    Rated 5 out of 5 by from I almost wish for cold & snow! It hasn't been cold or snowy enough for me to use yet, but I will say that it is extremely well made. I love its features: pockets, cuffs, high waist, reflective stripes, just to name a few. If I don't gain any weight, I know this will last me for as long as I continue to ride. Everything it advertises to be. I should add it is very warm with room for multiple layers.

    Rated 5 out of 5 by from Excellent winter warmth with full seat security This is my second pair of Mountain Horse Polar Breeches. I used the first pair for many years of winter riding until the fabric began to wear thin.

    Rated 5 out of 5 by from Great winter pants These fit a bit small so had the go up a size. A size 8-10 is a medium. Lol e these, great quality, can't wait for winter!

    Rated 5 out of 5 by from Great improvement I have a pair of winter Mountin Horse pants and jacket from about 15 years ago. The pants from way back when are comfortable, warm and fit great. The only complaint is they were not long enough for riding purpose when put over boots. The new pair I just got is great, many improvements, love it. I read all reviews and got size small so I can wear pants underneath, otherwise I would fit into size xs. Love the way the look, fit and all the little improvements. Winter can come now !

    Rated 5 out of 5 by from Could not survive winter without these! This is my second pair of mountain horse winter pants. My first pair lasted about 6 years and I wear them everyday all winter long. I could not survive these freezing cold winters without them! They are warm and comfy and you can also just hop on and ride without being too baggy. Love Love Love these pants! Very excited that I got them at the end of the season for 50% off! Thank you Smartpak!

    Rated 1 out of 5 by from Sizing Chart specs not same as actual product Bought the XS Mountain Horse Polar Breech. The size chart said it would measure 29" waist/ 39" hip/ 31" inseam. I have to shorten everything so the inseam was not a critical measurement, it was the only one that matched the product! The actual waist measurement was 26" and the hip 38". Disappointed.

    Rated 5 out of 5 by from nice but too long Really nice ski pant type breech. I would have loved to wear them but alas I'm short and fat and they were too long...way,way too long. The large fit fine- except for the legnth and I didn't want to go through the hassle of getting them professionally shortened. Super well made and would have been perfect for winter riding or other activities where a warm ski pant was needed. Smart Pak's return poilcy is quick, seemless and a joy to deal with.

    Rated 1 out of 5 by from poor customer service I ordered two pair of Mountain Horse Polar Breeches, I received a invoice stating that they were in stock and being shipped the next day, when I didn't receive them I called the company, they said they were sorry but they ran out of stock and wouldn't get them back in stock until August and this is February.

    Rated 5 out of 5 by from Best Buy of the year I needed a warm pair of breeches to get me thru the winter. Saw these on sale and thought I would give them a try, Best Buy I did all year. They are warm, water proof and I go from catching horses in the snowy fields to the saddle without taking my snow pants off, love them

    Rated 5 out of 5 by from Just what I needed! Needed a hard-core winter breech for Wisconsin Winter rides. Love the full-seat breech feature - makes is easier to train without getting cold. It has great insulation, fits well with a variety of boots, and the adjustable fitting features make for a truly comfortable fit. I am 5'2" and the XS is perfect in length! Thank you for being about the only site that carried clothing in XS!!

    Rated 3 out of 5 by from I returned these pants today. They were comfortable and warm but the top snap on the belt popped off when I tried them on for the first time. My arthritic fingers had a difficult time with the side zippers on the pant legs. I love Mountain Horse products. These pant are just not for me.
