Radical ULZ is made for those who pack fast, sleep wherever they land, and don’t carry anything they don’t need.
It weighs just 350 g and packs down to 2.5 liters. We filled it with 900 CUIN RDS-certified goose down (95/5) – the same down we use in our expedition models. The chambers have a simplified construction, so the down lofts quickly on its own and helps prevent cold spots from forming.
The outer shell is made from GELANOTS® Ultra Light Rip Stop – a lightweight fabric that resists moisture and won’t tear easily if snagged.
We’ve also used our Humidity Management System (HMS) – a construction method that improves moisture wicking and helps maintain a dry microclimate inside the bag.
A short YKK zipper makes it easy to get in and out, even in a hurry. On the outside, we added hanging loops for drying, and included two storage bags: a compression sack and a mesh bag for longer-term storage.
Perfect as an ultralight summer bag or as part of a layered system. Especially if you want to carry only what truly need.
