The Richardson by MOOSE KNUCKLES has all the tools it needs to keep you warm no matter where you live. The Bluesign certified organic cotton/recycled poly shell is treated with DWR (durable water repellent) to resist water and wind while remaining breathable to prevent overheating. And there's no cold on earth (at least where people live) that their RDS (Responsible Down Standard) certified 800FP 90/10 down can't handle.
