What Our Gearhead(R) Experts Are Saying: "I use this tee for pretty much everything-gym sessions, approach hikes, and long climbing days. It dries fast, stretches well when I'm reaching or hiking uphill, and doesn't get that funky smell as quickly as most tech tees." When the day's agenda includes a little bit of everything, we pull on the Lightwire Short-Sleeve Tee and don't think twice. Designed by Black Diamond to move seamlessly between climbing, trekking, and training, this tee delivers breathable comfort that keeps up when the pace and effort change throughout the day. The four-way stretch fabric moves easily with dynamic movement, while underarm gussets and raglan sleeves reduce restriction when reaching overhead or carrying a pack. Quick-drying, moisture-wicking performance keeps sweat in check, and an anti-odor finish helps the tee stay fresh on long, active days. Finished with reflective logos for low-light visibility, the Lightwire is a dependable layer for training hard and staying comfortable.
