Arc'teryx sizes are intended to fit the body measurements above. If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit. Arc'teryx has recently updated the men's fit: medium remains unchanged, smaller sizes now fit tighter and larger sizes now fit looser.

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
How do I wash it?

Arc'teryx have not published the care panel for this style yet. Follow the label in the garment, and we will add the full instructions here as soon as the brand publishes them.

How does it fit?

Arc'teryx call this a relaxed fit. Check the Arc'teryx size chart linked on this page before ordering.

Is it actually waterproof?

Yes. The shell is built on a GORE-TEX laminate, which is waterproof and windproof rather than merely water-resistant. Seams are taped. The PFAS-free DWR on the face fabric keeps the outer layer from soaking through, and it can be refreshed with a wash-in or spray-on treatment when water stops beading.

What does the Arc'teryx warranty cover?

Arc'teryx warrant their garments against defects in materials and workmanship for the practical lifetime of the product. That covers manufacturing faults, not wear and tear or accidental damage. Bring it to us and we will help you start the claim.
