Women's Mountain Side™ Heavyweight Fleece is rated 4.8 out of 5 by 168.
Rated 5 out of 5 by from Ary I love this Jacket, I’m medium and it fits perfect so they run a true size. It’s warm, I was expecting to have fleece on the inside too but is not, nice material and looks very pretty. I got the black one and looks great! I bought it on sale so I love my purchase

Rated 5 out of 5 by from SO COZY I’ve been eyeing these furry coats for awhile. I have a Patagonia one and its just the same. I personally like these better, it insulates the heat better. I do recommend getting a size bigger because it can feel a bit tight. But other than that, I love this sweater!

Rated 5 out of 5 by from Great Jacket I wanted a new Fleece for my trip to Iceland. I really like the style of this jacket and bought it. I am really happy I did. It was a good looking jacket and perfect for cool weather, but not over hot. I really liked the way it looked on and even the color chalk with navy accents.

Rated 4 out of 5 by from Would have loved a softer lining The jacket is comfortable and of a nice heavyweight, but the inside has rough seams unlike most fleece that feel nice on your skin. I would recommend this jacket as long as you plan to wear with long sleeves underneath.

Rated 5 out of 5 by from Great fleece I am usually a size small but I like my jackets a bit bigger so I went with a medium and it's perfect. The material is super soft and warm and feels great against your skin. It looks really great on too. Since buying it, it's been my go-to fleece jacket and probably will continue being for a long time.

Rated 5 out of 5 by from WOMEN'S MOUNTAIN SIDE™ HEAVYWEIGHT FLEECE I love this jacket. Living in Vermont it gets very cold and this jacket is awesome for colder weather. As I mentioned in another review I indicated it runs a little small. This is because last year I purchased a jacket in medium and it was and still is roomy and I had to size up to a large with this. Other than that it's a great jacket and excellet quality.

Rated 5 out of 5 by from Great fit I really like this cozy jacket. The placement of the pockets that other reviewers have complained about is not as bad as they make it out, just my opinion.

Rated 5 out of 5 by from Great Fleece Jacket I have been looking for a good quality fleece jacket and I found one. Even though it said Heavyweight, it is not heavy but it is thicker then the usual fleece jacket with good quality. I have worn this jacket to where the temperature is in the 30's and still comfortable! Great product, Kudos to Columbia Sportwear!!

Rated 5 out of 5 by from Heavyweight Fleece Review BEST PURCHASE I’VE EVER MADE. Great jacket, warm, but light. I take this jacket with me everywhere. Good material. I’m sure to make my family a Columbia wearing family. Truly worth the buy!

Rated 5 out of 5 by from Warm Just wore it this weekend and not only is it warm, it's attractive. Some speak of how the pocket entry is way back and this is true. But they are deep & swallowed my large phone without a bulge. Definitely didn't have to worry about it falling out. I love it. Brought 2, keeping both.

Rated 4 out of 5 by from Very warm This is a NICE, WARM jacket. “Cuffs” around wrist are a little small. Not as roomy there as I’d like (and I have very small wrists). I got size small. I’m normally a size 0/ XS. The Small fits me perfectly so I would rate this as running small. Overall a stylish, warm jacket.

Rated 5 out of 5 by from WOMEN'S MOUNTAIN SIDE™ HEAVYWEIGHT FLEECE I saw this jacket last Fall and fell in love with it but decided I didn't need another jacket. When it went half-price it was a done deal! The jacket isn't what I'd consider heavyweight and I was skeptical whether it would be warm when the temps were in the 30s. It arrived during a frigid stretch of weather when the highs were low 20s and with a long-sleeved t-shirt and fleecy pullover it was perfect! Couldn't believe how warm I was. I normally wear small and sometimes extra small and ordered small based on the sizing chart and the fit was good. The pockets are in the side seam and somewhat awkward. I'm also 5' and the hem was at my lower hips. The quality and workmanship is good and the hems are nicely finished. It isn't lined like a typical jacket - the fleece is bonded to a slightly stretchy fabric - so there are raw edges inside. Cleaning instructions are machine wash, tumble dry (no dry clean, no fabric softener, no iron) so care instructions are pretty easy. This jacket is a keeper!

Rated 2 out of 5 by from disappointed I was really excited and looking forward to arrival of this fleece. The title of this item stated heavyweight, but the actual product is thin. It's not as warm as I had expected. I would return it, but the cost of shipping is ridiculous, which is why I'm keeping it. Second purchase I've made from Columbia, and both were disappointing. Not sure if I'd buy from here again.

Rated 5 out of 5 by from Excellent choice I love my Columbia Mountain Crest jacket. Warm enough for the winters in Kentucky. I also ordered my husband one I liked it so much.
Date published: 2018-01-24
Rated 5 out of 5 by from Buy it I get cold very easily and this fleece has filled a major hole in my wardrobe. It is warm and cozy on its own, but also perfect for layering if you size down a bit. I am 5'8 and 140lbs and usually wear a medium, but based on other reviews, I ordered the small. This has turned out perfectly for me. I can wear a sweater under the fleece and use it as a jacket. Or, in colder weather (10s-30sF), I can fit it under my puffy down parka. (Other people who don't chill so easily could comfortably wear this in much colder weather, I suspect.) The fleece is very lightweight and easy to pack away on hikes, if necessary. It is also possible to stash keys, phone, wallet, etc. inside the jacket in the de facto pockets created by the actual pockets intended for warming your hands on the outside of the jacket. (In other words, lining doesn't cover up the inside structure of these pockets inside the jacket.) After this purchase, I have actually been warmer than my husband on a number of occasions, which has never happened before. I bought the fleece on deep discount, but it is absolutely worth the full price.

Rated 5 out of 5 by from Cozy and Warm I love this jacket...Received many compliments. Cozy and Warm enough to wear by itself on 40 degree temps. I normally wear a size 8 in jackets and ordered this in a medium. It fits snuggly and I can't really wear a sweater under it. I may order a large one to have in case I want to wear something heavy under it.

Rated 4 out of 5 by from Awesome Love this coat! It’s warm and cozy, love the look too. The only reason I didn’t give 5 stars is because the pockets are a bit far back, putting hands in pocket is slightly uncomfortable for this reason. I’d still recommend though!
