Bring a lightweight layer of insulation to your fitness practice with the Altitude Tracker 1/4 Zip for men. Comfy enough for weekly wear, and packed with details that make it as strong as it is stylish. So you can take it beyond the gym too. It's made with a 4-way stretch fabric, which means it rebounds quickly to keep its shape. It has UPF 50+ sun safety and moisture-wicking properties to keep you cool and confident. And just when you thought it couldn't get any better, we add in thumb holes to each cuff to keep your sleeves in place, and a concealed zip pocket for a safe spot to stash your keys and cards.
