Perfect as a warm base layer or as a top layer over a thinner shirt, this long sleeve Nike shirt is so good for everything. I’ve hiked cold mountains in Utah in this and didn’t feel at all chilly. The zippered high neck is perfect to keep you bundled up and cozy, and when you start to warm up, you can unzip along your clavicle/shoulder. The zipper is small but incredibly sturdy and pulls smoothly, which helps when you’re on the move. The embossed pattern is a subtle snakeskin, giving it fashion and flair. Thumbholes in each arm and is slightly longer in the back than the front for extra warmth. Very well made and meant to last. Top Size: M Color: Purple; Striped Style: Long Sleeve Pullover; Quarter Zipper Material: 88% Polyester; 12% Spandex
