Great piece! Perfect for hotter days.
The Summer Baselayer is very comfortable and has a nice amount of stretch. The fabric feels very durable and just premium in general. The cut is a little shorter than some other baselayers I have, but the stretch helps make up for it. If you live in a very hot climate, it is a little thick/warm for the hottest summer days (anything over 90). Overall, it is another solid Ornot product with fantastic material.
As a very vocal advocate of base layers it's hard to talk people into using them indoors (which I do) and outdoors when the temperature exceeds about 80F (which I do). This is the answer. This lightweight base layer is an absolute lifesaver when the temperatures heat up and you still need that base layer protection and sweat wicking brilliance. Plus, it's made ethically from dead fabrics and is carbon neutral. And it even IS the color of carbon. What's not to LOVE?
