Lightweight. Long sleeve. Built to move.
The Vayper Long Sleeve is your go-to for exposed trails, high-output efforts and anywhere you need performance without bulk. The fabric is smooth and featherlight — barely there against your skin, but built to work hard in the heat and under pressure.
Its athletic cut keeps it snug against the body to wick moisture efficiently, whether you’re powering uphill or covering long miles in the saddle. And while it excels in the heat, it’s just as effective as a base layer when the forecast turns.
Lower impact. Higher mileage.
Woven from 100% recycled fibres and treated with Polygiene® odour control, the Vayper Long Sleeve lets you do more with less — less packing, less washing, and less environmental impact. It’s the kind of top you’ll wear on repeat, from spring ridge days to summer thru-hikes and beyond.

How to measure
This size chart indicates the body measurements our garments are designed to fit. Measure yourself as described below, and use the size chart to find your size:
Chest - measure around your chest at the widest part. The tape measure should pass under your arms, and be level from front to back.
Waist - measure around your waist at the narrowest part.
Sleeve - With your arms relaxed by your side, tilt your head down and ask a friend to measure from the bone at the base of your neck, over your shoulder and down your arm to the fold at your wrist.
