Pajak - Radical ULZ (0°C)

Down sleeping bag (0°C)

The Radical ULZ is designed for people who pack quickly, sleep wherever they land, and take nothing they don't need.

It weighs just 350 grams and packs down compactly into a 2.5-liter bag. We've filled it with 900 CUIN RDS-certified goose down (95/5) – the same down we use in our expedition models. The compartments have a simplified construction, allowing the down to quickly expand naturally and preventing cold spots.

The outer shell is made of GELANOTS® Ultra Light Rip Stop – a lightweight fabric that repels moisture and doesn’t tear easily when it gets caught on something.

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 things in and out of the bag, even when you're in a hurry. We've added hanging loops on the outside to let the bag dry, and included two storage pockets: a compression sack and a mesh bag for longer-term storage.

Perfect as an ultralight summer sleeping bag or as part of a layering system, especially if you only want to take what you really need.
