See our entire range from Pajak here!

Pajak RADICAL 16H Long is one of the world's warmest down sleeping bags , designed for professional winter expeditions in polar regions, high alpine environments and extreme cold where equipment must perform without compromise. The Long version is specially adapted for taller users and combines maximum warmth with surprisingly low weight.

The sleeping bag is filled with 900 Fill Power RDS-certified Polish white goose down (95% down / 5% feather) , which provides exceptional insulation per gram. The construction is based on Pajak's advanced HH construction - double H-shaped chambers in two offset layers - which effectively eliminates thermal bridges and creates even heat around the entire body even in extreme cold.

The RADICAL 16H Long is also equipped with an Infrared Reflective Layer (IRL) , an infrared reflective layer that retains up to 50% of the body's heat radiation , which significantly increases thermal efficiency in sub-zero temperatures. The outer fabric in GELANOTS® Ultra Light Ripstop Shell is both very durable and water-repellent, while maintaining low weight and good breathability.

The anatomical mummy shape , generous thermal collar and hood with one-hand adjustment mean that only a minimal part of the face is exposed. The sleeping bag is equipped with 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 despite the extreme insulation.

RADICAL 16H Long is tested according to ISO 23537 and specified for temperatures down to −73 °C , making it the first choice for serious expeditions where sleep is crucial for safety and performance.
