Radical 1Z is for those who pack light, sleep where the night finds them, and don’t carry more than they need.
It is filled with 235 g of premium Polish goose down with 900 CUIN fill power – the same used in Pajak's expedition models. It insulates, breathes, and keeps its loft even after many intense seasons. RDS certified – so you know it comes from a responsible source.
The outer fabric is GELANOTS® Ultra Light Ripstop with a hydrophobic coating – it doesn’t soak up water and resists moisture and abrasion. The integrated HMS (Humidity Management System) keeps the microclimate inside the bag dry.
Z-baffle construction eliminates cold spots, and the close-fitting mummy shape traps warmth efficiently. The YKK zipper opens and closes smoothly, and an insulated baffle blocks cold air. Inside, there’s a pocket for your headlamp or phone; outside – loops for drying.
Performs best around 5°C, and even lower with proper layering. Ideal for tarp camping, ridgelines, or bikepacking adventures.
