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.

Sustainability and Product Care

How It Is Made

Polygiene® Stay Fresh
Polygiene® Stay Fresh technology inhibits the growth of pong-causing bacteria, extending your tee’s lifespan and meaning you can wear it more and wash it less. Wearing your tee just one more time before washing can save huge amounts of CO₂ and water over its lifespan.

Where It Is Made
Our products are made in the best factories in the world. We know the factories personally and they have all signed up to our Code of Ethics in our supply chain.

Reducing our carbon footprint
We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.

We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.

End of life
When your partnership with this product is over send it back to us and we will pass it on to someone that needs it through our Continuum Project.

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.
