Awesome, runs small

  • Familiarity: I've used it several times
  • Fit: Runs small

I've never understood why it's so hard to find a fleece or merino sportsbra, because they are the bomb for skiing, snowshoeing, and any other winter sport, whether you do them aggressively enough to sweat or no. SmartWool's is good because the exterior layer is a poly fabric that keeps the wool inner layer from stretching out quickly. Fit: rides a bit high--that is, the band is juuuust low enough to stay put (and friends who got it confirm this). Size UP. By Smartwool's chart, I'm either an S or M (34B) but I needed an M, maybe because of big shoulders. But petite friends who are S or M by the chart (34A) also needed M. Main reason for sizing up is for comfort of straps around armpits and security of the band not riding up. I just wore it for a week and a half straight and now it's finally a bit stretched out. No smell, though. :-) It would be nice if they would go back to making more colors. I am so tired of default black.
