Rab Radeon -12°C Sleeping Bag – Technical Synthetic Sleeping Bag for Trekking and Cold Mountains

Description

The Rab Radeon -12°C is a synthetic sleeping bag designed to offer reliable warmth, resilience, and peace of mind in cold and variable conditions. Compared to a down bag, it better maintains its performance when humidity, condensation, or prolonged bivouacs complicate the outing, making it a very solid option for trekking, backpacking, and regular mountain use.

Real Technical Performance

Its recycled Stratus™ insulation and WARM WAVE™ construction create air pockets that help retain warmth without excessively penalizing weight. It's a bag designed for those who prioritize real reliability in the field: cold bivouacs, damp camps, multi-day treks, and frequent use where durability and ease of maintenance truly matter.
