Is this right for you?

Long days on the water

Crossover hood and thumbholes cover the neck and back of hand - the spots that burn first when you are out from dawn to dusk.

Not for: UPF 20+ is lightweight protection rather than the highest rating available.

Hot and humid hiking

At 145 GSM it breathes hard and dries fast, and bamboo viscose resists odour so it stays wearable over several days out.

Not for: Not a warmth layer - it blocks sun, not cold.

Everyday wear

The reason it has over 3,600 five-star reviews: it is soft enough to live in and cut slim enough not to look like technical kit.

Not for: The crossover hood sits high, which some people find warm off the water.

Questions, answered

Before you buy.

Pulled from chats, emails and store visits. The things people actually ask us before they buy. Don't see yours?

Ask a question
Will it shrink after washing?

Because of the quick-dry benefits of the Bamboo Breathe fabric, this piece shrinks slightly after the first wash. Free Fly sizes it a touch larger to accommodate — try it on before washing and you should have a little extra room.

What does the UPF rating mean?

UPF measures how much UV radiation a fabric blocks — the higher the number, the more sun protection. Check this style's specs for its exact rating, and remember that coverage features like hoods and thumbholes extend that protection.

How should I wash bamboo fabric?

Turn it inside out and machine wash cold on the delicate cycle, then hang dry. Skipping the dryer preserves the buttery bamboo feel and extends the life of the garment.

Can I check this out in person first?

Absolutely — stop by Mountain Sports and we'll set it up so you can try before you buy. And everything ships with free 30-day returns if it's not the right fit.
