Mountain Hardwear Butter Zippy Top - Women's - 2007 BCS

I love the roomy fit and the softness. This shirt has kept me warm and dry after cross-country skiing and hefty hiking. I'll buy another!

This shirt is so soft and well fitting that it has moved to the top of my collection for a first base layer. It wicks moisture well to keep me warm and dry when I go from working up a sweat on a bump run to riding the lift. Couldn't ask for a better base layer; definitely worth the investment.

My sister got this for me for christmas, and I couldn't be happier! It's soo soft, and warm! I use it as a layer when Im snowboarding, or just as a top layer on a cold day! two thumbs up for sure!

The shirt is too short and makes me question MH's ability to design for woman. I love the button-up butter if you need length. it is nice and long. The zipper on this one irritated my neck, so I would not recommend it for people with sensitive skin or seam-issues. I am 5'10/145 with sensitive red-head like skin.

I use this top as a base layer for skiing, but it could easily be used for other sports or workouts. Used alone, it is a very attractive piece of technical wear. It stays dry and, for me, is the perfect weight for a first layer. It is very soft, stretchy and form fitting so there isn't a lot of bulk, and bunching up, which I like. For what it is (meaning a technical top with spandex), I believe it runs true to size. If you don't like things too clingy, go up one size.

I love this shirt! It's quite warm for the weight and very soft! One of my favorites so I have 2!

This shirt is nice and soft, but if you want it for the thumb holes, you better have shorter arms than I do. I am 5'10'' and 130 lbs. I bought the small, which mostly fits ok, but after just a few hours of skiing with my thumbs in the thumb holes, my thumbs were just about ripped off. If you're tall and thin it's hard to get great-fitting gear. This is one more to steer away from.

Loved the material but sent it back b/c the torso was too short. i'm 5'6" 110# short torso. if you don't mind your shirt pulling out, riding up then this could be perfection. should have purchased a XS instead of M for proper snuggness (and i'm large chested)IF it had not been so short. I've use MH clothing alot and this was way too short-Bummer :(

Truly an amazing shirt. Aside from the soft fabric, it is quite wind resistant and works as a great outer layer for running and hiking on mild days. My only complaint is the same one I have for all microfiber type shirts...they stink after about 1/2 day of wear. No deodorant can fix the way this fabric absorbs odors. Note: the hoody version is not cut the same at all, with a broader, shorter torso. Just because one fits doesn't mean the other will.

This is my favorite under layer top. The description is totally accurate - buttery & warm. It fits so well, I actually wear it as a going around town top.

I love the soft feeling of this "butter" fabric. This top fits well and is a great light-weight mid layer. Nothing to complain about. Recommended for temps 50F and below.

i bought this for my AT through hike next march, but have been wearing it when i run on cool days. really soft, great fit.

Ok, so I own three but who's counting. I love this shirt for just about anything. I like it better than the hoody cause the neck fits really well. This is a great layering piece or stands well alone as a nice zip neck. I wear this all winter, both on the hill and to work. I also wear it as a nice pullover for those cooler summer nights. The fabric is amazing and you will not find much better than this. It's like butta....
