So far I used it once, very comfortable for outdoor adventure!
I was looking for a shirt that would protect me from nasty scrapes and scratches of climbing, particularly at my gym where the walls have the texture of 60 grit sandpaper. While being as comfortable and flexible as possible. I found it in this shirt. It takes the abuse, looks good, and feels great.
I wore this under a back protector whilst skiing. Great length arms and a nice soft feel. I knocked one star off because the neck has zero give, possibly a design feature of the spectra fabric? Overall though, a very nice item with colors true to those on the website.
