This is a function-forward T-shirt, focused squarely on doing a single job really well: helping your performance during athletic pursuits no matter how sunny it is outside. We used it for workout runs on asphalt pavement and other roll-up-the-sleeves tasks, such as loading kayaks and setting up our basecamp.

The solar shielding was great, as our torso didn't even get a hint of a tan. However, the material didn't seem to disperse heat as well as some of the other shirts. Compounding the problem, once we got really hot the fabric had a tendency to stick to our skin. On the plus side, the waffle texture allowed it to dry quickly as soon as we cooled down.

This shirt is close-fitting, but the way the pieces are stitched together combined with the stretchy nature of the polyester, still allows for great flexibility. We could confidently wear this shirt on a cloudless backcountry hike, or during a manmade disaster in the middle of summer. Our only caveat: order one size up if you don't want to look like you shop at Baby Gap.
