Salomon
Long Sleeve Exo Motion 1/2 Zip Tee (Men's)

I love the material and fit of this shirt. It fits tight, so you may consider a size up. The material is light, breathable, and works really well as a base layer. It's also long at the bottom so the shirt won't rise or lift if you're running or working out. There are two negatives that I didn't like about the shirt, mainly the sleeves and the collar when fully zipped.

I purchased this in a size small, but the sleeves were way too long. You'd need to have gorilla arms, otherwise all the material bunches up in a clump near your wrist. Also, when the 1/2 zipper was up all the way, the zipper would hit my neck and I would consistently have to tug the shirt down to alleviate the pressure. Aside from that, I would've really liked the shirt, but those were big issues for me. Thank you to Rock Creek for an easy return!
