Top materials, clever construction, comfortable details

The Lithium’s Pertex-Quantum outer is 100% recycled and is super functional. The down used is RDS-certified and has a PFC-free, water-repellent treatment to prevent it from clumping up.

The Lithium mummy sleeping bag’s most special features include the curved down baffles that prevent the fill from slipping, the anatomically optimized fit at the head and the foot box, the dual zip for easy entry and its special zip slider that prevents jamming when opening and closing.

The highlights at a glance:

  • First-class 800+ cuin goose down located in S-shaped baffles to prevent it from slipping
  • Nautilus hood and 3D foot box enhance comfort and thermal efficiency
  • Special zip system for optimal ventilation and easy handling
