I nvista Quallofil: Thermal material in synthetic polyester which is used to fill high-end sleeping bags.It insulates thanks to hollow fibers which retain air as an insulator. The fiber dries quickly, is light and durable. It keeps heat even when wet. It allows you to achieve great lightness and retain warmth without increasing the weight or volume of the sleeping bag.

Anti-slip strips: The added value of Husky Extrem sleeping bags is increased thanks to the anti-slip strips on the lower part of the bag. They prevent slipping on the floor mattress and are a particularly practical detail if you sleep on uneven terrain.

RipStop material: The RipStop material is characterized by its high resistance to mechanical damage. The special grooves considerably increase its resistance against cracks. However, if the material is damaged, RipStop prevents it from further deterioration.

Inner anti-cold collar: The anti-cold inner collar is part of all Husky sleeping bags, except the lightweight models. It is used to maximize thermal comfort when it is cold. It is very easy to handle. Once properly installed, simply tighten the collar around the shoulders and lock it with a small plastic brake.

Materials: Husky sleeping bags are filled only with branded materials from renowned manufacturers. The Husky Extrem range is insulated by Invista Quallofil 7-channel fiber, or even by Thermolite Extreme or Thermolite Micro hollow fibers.
