Grüezi BagBiopod Downwool Hybrid Ice Cold - Sleeping bag

The technical sleeping bag Biopod Downwool Hybrid Ice Cold from Grüezi Bag combines goose down insulation with alpine wool to keep you warm during your cold mountain adventures. Its hybrid construction emphasizes an even distribution of warmth to withstand the harshest conditions.

Equipped with high-quality goose down with a fill power of 800+ cuin and a layer of alpine wool, this bag absorbs moisture, helping to maintain the loft and insulation of the down. The integrated carbon heating element provides extra warmth to the feet, powered by an external battery for added comfort in freezing weather.

Ideal for mountaineers and winter hikers, this model stands out with its comfort fit, offering great freedom of movement.
