Made from a 100% recycled polyester fabric that’s incredibly soft, light and fast-drying, the Vayper is designed to be a true next-to-skin base layer, ideal for a range of high output activities. The close, athletic cut allows the Vayper to pull sweat away from the skin much more rapidly when you’re working hard and the ultralight fine knit fabric retains less moisture, meaning it dries quicker. Polygeine® treated fabric keeps the Vayper pong-free after multiple uses and allows you to go longer between wash cycles.

Highly effective as a cool standalone layer in milder conditions, the Vayper also fits neatly underneath midlayers and bike jerseys as part of your layering system. Despite its silky ‘barely there’ feel, when worn underneath layers the fabric traps narrow pockets of still, warm air, adding extra warmth without the bulk.

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. This includes the Ethical Trading Initiative base code, fair pay, safe working environments, no child labour, no modern slavery, no bribery or corruption, no materials from conflict zones and humane farming methods.

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.
