Combining 800FP goose down with heat reflective TILT technology and a GORE-TEX INFINIUM™ WINDSTOPPER® outer, the Andes Infinium offers an exceptional warmth to weight ratio ideal for expeditions in freezing conditions. This women's bag has a shorter length and female specific shape to improve efficiency.

Offering refuge to those exploring the world’s highest peaks and the polar regions, the Andes Infinium is packed with cutting edge tech, built to keep you warm.

The Andes Infinium 800 is filled with 800g of ultra-high lofting 800FP, goose down. It is constructed using trapezoid shaped boxwall baffles, which stack together reducing cold spots and maximise the lofting and efficiency of the down inside. Reflecting heat towards the body, our TILT technology is seen as a silver sheen on this inside of the bag. Reducing heat loss by up to 32%, TILT substantially improves thermal insulation without compromising pack size, breathability, or weight.

It has a mummy fit and offers a similar level of warmth to our Expedition range of sleeping bags, but in a lower bulk package. The women’s specific cut is fractionally shorter than the regular bag with a narrower shoulder and marginally wider hip space, for comfort and efficiency.

The GORE-TEX INFINIUM™ WINDSTOPPER® outer provides a robust, windproof shield against icy chills, and the face baffle and 3D neck collar cinch in snug around the face to seal in the heat. The ¾ length YKK® zip has its own internal baffle to avoid heat escaping and an angled foot box allows for a comfortable sleeping position.

Hand-filled in the UK, all our down bags benefit from never having had their down compressed before use, maintaining the down’s loft and warmth.
