The long-sleeve Salomon Whisper II shirt offers motivational comfort in the gym, on the trail and everywhere in between. Incredibly lightweight polyester/elastane blend fabric transfers moisture from your skin to the outer fabric surface where it quickly evaporates. Fabric provides UPF 50+ sun protection, shielding skin from harmful ultraviolet rays. Flatlock seams maximize motion and minimize abrasion. Reflective detailing increases visibility in low light. Salomon Whisper II shirt offers an active fit that's not too tight and not too loose.
