At Grüezi bag®, comfort and functionality are key. This sleeping bag:

• provides an evenly pleasant sleeping climate;
• features a comfortable cut for freedom of movement;
• is lightweight and compact for easy packing.

Comfort climate

DownWool® insulation ensures you are never too cold or too warm. The patented down and wool mix acts like a natural air conditioner, balancing temperature and maintaining a dry microclimate.

• High-quality down delivers excellent insulation with minimal weight.
• Wool keeps down naturally dry, avoiding chemical treatments and preserving warmth.
• Wool absorbs up to 30% of its weight in moisture, releases it gradually, prevents evaporative cooling, and regulates body temperature while neutralizing odors.
• DownWool® reduces energy spent on temperature regulation, leaving more for recovery.
• Provides excellent insulation and a wide comfort range, making it a versatile all-rounder.

Cut

The comfort cut allows restful sleep in mummy shape, side-lying, or turning within the bag.
