This has become my go-to shirt on warm weather days especially if there's rain in the forecast. I section hike the Appalachian Trail (AT) quite a bit and I always wear this over a 2 day period (same one). This thing stands up great to the conditions of the wet forest and despite the friction near my backpack hip/shoulder straps, there's no wear and tear after 75+ miles. I'm never hot in this thing as it breathes so well despite form fitting to my body. It stretches where needs to and does not limit movement. This is a beast of a shirt.
