I recently wore this on a cooler climbing day and it fit perfectly. It breathes so well, which was awesome for the strenuous approach. I'm a 34DDD and the stretch was perfect enough that it wasn't too tight and is super flattering. I'm having a tough time not wearing this shirt everywhere, everyday. Comfortable, versatile, and bomb for climbing in.

While this item is a nice layer, the sizing is really bad. The Medium/Large is still too small for somebody who is typically a medium in Black Diamond and most other clothing vendors. Careful on sizing! Fortunately Backcountry is being gracious and letting us return it, and because of this we are still so happy to shop with Backcountry.com - even if Black Diamond sizing is so wacky.

I wear this thing everywhere: to the office, on a trail run, on the side of a mountain, up some slab...you name it. It has a really flattering fit and it's stretchy. It's a great base layer or just something nice to wear in slightly cooler temps. I would say that this runs small. I usually wear a small but I always have to size up in BD apparel so I would say it's consistent for their sizing.
