Whether you’re moving fast on exposed ridgelines or cruising dusty gravel roads, the Vayper Long Sleeve gives you lightweight performance with added protection from sun, wind and pack rub.

  • 100% recycled polyester – soft, ultralight, and fast-drying

  • Long sleeves for added sun protection and trail comfort

  • Polygiene® Stay Fresh tech – wear more, wash less

  • Fine knit traps warmth under layers, breathes beautifully on its own

  • Close fit pulls moisture away when you're working hard

Full coverage. Featherlight feel.

Made for high-energy days in wild places, the Vayper Long Sleeve offers everything you love about the original – with extra coverage where it counts. The silky-soft recycled fabric is gentle next to skin, even when the sun’s high or the terrain’s demanding.

It’s designed as a true next-to-skin base layer, with an athletic fit that wicks sweat fast and keeps you cool as you move. And when the temperature drops or the breeze picks up, those long sleeves offer lightweight insulation and comfort under midlayers or jackets.

Kind to skin. Kinder to the planet.

Made entirely from recycled fibres and treated with Polygiene® odour control, the Vayper Long Sleeve helps you pack light, stay fresh, and tread lighter. Ideal for multi-day missions, long climbs, or simply avoiding sunscreen reapplications — it’s a versatile essential for all-season movement.

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.
Hips - Standing with your feet together, measure around your hips at the widest 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.
