Grüezi Bag Biopod DownWool Extreme Light 185 Sleeping Bag
ULTRALIGHT SUMMER SLEEPING BAG WITH EXCELLENT COMFORT AND A TINY PACK SIZE.
Weighing just 500 grams and packing down to 13 by 18 centimetres, the Biopod DownWool Extreme Light is an ideal summer sleeping bag for trekking, biking, camping, or staying in huts.
Its unique DownWool insulation combines down and wool to keep you comfortable without getting too hot or cold. Down provides excellent warmth but loses its insulating power when wet. Wool absorbs moisture and keeps the down dry naturally, so no chemical treatments are needed.
Wool also regulates temperature by slowly releasing moisture, keeping you warm even when wet. It also reduces sweat odours to keep your sleeping environment fresh.
This natural insulation helps your body save energy by maintaining temperature more easily, allowing you to rest better. The Biopod DownWool Extreme Light offers great warmth and comfort across a wide temperature range, making it a versatile choice for summer adventures.

Size : Mummy sleeping bag with 215 x 80 x 50 cm (suitable for a body height of 176 cm to 190 cm with a normal stature. For people with a wider stature, we recommend the larger sleeping bag version from 185 cm tall.)

Packing volume : 3 litres, compressed 2.5 litres
Outer and inner fabric: Ultralight, durable and recycled 20 denier 380T nylon (100% polyamide) that feels incredibly soft, supple and silky on the skin. This is achieved by pulling the fabric over hot rollers to constrict the pores. This makes the fabric down-proof, impermeable to clothes moths and still remains naturally breathable without the usual plastic coating. The pores do not stick together either due to the bio-based BeSoDRY-ECO impregnation or the sustainable BEMACRON dyes. The outer material is therefore windproof and highly water-repellent.
Filling : 195 g DownWool® made from 70% high-quality duck down (90/10 with fill power at least 650 cuin) and 30% mechanically refined wool
Material identification : Shell 100% polyamide, filling 70% down/30% wool - contains non-textile parts of animal origin.
