See our entire range from Pajak here!

Pajak RADICAL 16H Regular is an extreme down sleeping bag developed for the world's coldest environments , designed for high-altitude expeditions, polar travel and winter use where equipment must function without compromise. It is designed for use in the so-called death zone and is among the absolute warmest sleeping bags produced commercially.

The sleeping bag is filled with 900 Fill Power RDS-certified Polish white goose down (95% down / 5% feather) , which provides maximum loft and warmth in relation to weight. In the Regular size, the RADICAL 16H contains approximately 1,050 g of down and has a total weight of around 1,500 g . The advanced HH construction uses double H-shaped chambers in two slightly offset layers, which eliminates thermal bridges and ensures even heat distribution around the entire body.

The RADICAL 16H is also equipped with an IR Reflective Layer (IRL) – an infrared reflective layer that retains up to 50% of the body's heat radiation , significantly increasing thermal efficiency in extreme cold. The outer fabric consists of GELANOTS® Ultra Light Ripstop Shell with hydrophobic treatment, which combines very low weight with wind and moisture resistance.

The body-hugging mummy shape , a generous thermal collar and an anatomically shaped hood with one-hand adjustment mean that only a minimal part of the face is exposed. The sleeping bag has 3D insulated zipper baffles , tangle-free YKK zipper, inner pocket and internal and external hanging loops. Compression and storage sack included, with a packing volume of around 10 liters (Regular) .

RADICAL 16H is tested according to ISO 23537 and is specified for temperatures down to −73 °C , making it the first choice for professional expeditions where sleep and survival are intertwined.
