Re Wikstrom wrote a review of Mammut Fight-Gravity Tank Top - Women's on March 14, 2014
Familiarity: I returned this product before using it
Fit: True to size
Fabric seems to be great quality, seems like it would hold up to a lot of active use, is not overly thin and flimsy, and the shelf bra seems to have a little more support than most of it's kind.
I'm 5'5" 175 and have hips that are a size bigger than my shoulders. I tried on the XL. While this tank fit great in the shoulders, it was a little bit too skinny for my hips combined with it's length (I really liked the length, just a little too narrow for me at that length). I could go with the "scrunched" fabric look and it would work great, but I'm trying to constrain my gear buying habit to things that are 100% perfect for me, so I'll probably return it.
For anyone not overly pear-shaped though, I think this is a great top!
