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

Is the Rayu fully waterproof?

Yes — it pairs a 2-layer TPU laminate with fully sealed seams and a hook-and-loop storm flap over the front zipper for reliable waterproof protection.

How do I renew the DWR finish?

Wash the jacket clean, then tumble dry on low — gentle heat helps reactivate the DWR. When water no longer beads on the surface, reapply a spray-on DWR treatment.

Is it breathable?

Yes — a recycled polyester mesh lining keeps air moving so you stay comfortable on the move.
