Engineered for adventurers who demand performance without compromise, the Gruezi Biopod 8C DownWool Extreme Light 200 is an ultralight mummy sleeping bag tailored for summer applications where minimal weight and small pack size matter most. Designed for users up to 200 cm, this sleeping bag weighs only 600 grams and compresses down to a hand-sized compression sack (14 x 20 cm), making it perfect for trekking, bikepacking, and fast-and-light expeditions. Its standout feature is the innovative DownWool insulation — a unique hybrid that marries the warmth of down with the moisture-regulating and temperature-balancing qualities of wool, ensuring you stay dry and cosy even when conditions shift. Constructed with high-quality, PFC-free, water-repellent materials that meet OEKO-TEX standards and certified under the Green Codex, it represents a thoughtful choice for eco-conscious travellers. Designed for comfort and practicality, it features a pillow pocket, adjustable hood, and a footbox with ventilation system to help regulate temperature during warmer nights. Additional features like a two-way auto-lock zipper, zipper cover, white zipper for easy visibility, Feater loops, and integrated interior pockets boost usability whether you're out for a weekend escape or tackling multi-day missions.
