Providing a haven for adventurers of the world's highest peaks and polar extremes, the Andes Infinium is engineered with state-of-the-art technology to deliver exceptional warmth.
The Andes Infinium 800 features 800g of ultra-high lofting, 800FP goose down. Its construction incorporates trapezoid-shaped box wall baffles, designed to reduce cold spots and maximise the loft and efficiency of the down insulation. The innovative TILT technology, visible as a silver sheen on the bag's interior, reflects heat towards the user’s body. By reducing heat loss by up to 32%, this technology significantly enhances thermal insulation without increasing weight, compromising breathability, or inflating pack size.
Designed with a mummy-shaped fit, it offers warmth comparable to the Expedition series of sleeping bags, but with less bulk. The GORE-TEX INFINIUM™ WINDSTOPPER® outer fabric acts as a durable, windproof barrier against freezing gusts, while the face baffle and 3D neck collar ensure a snug seal, trapping heat inside. The ¾ length YKK® zip is accompanied by an internal baffle to minimise heat escape, and the angled foot box promotes a naturally comfortable sleeping position.
Hand-filled in the UK, these down bags maintain their loft and warmth by ensuring the down is never compressed prior to use.
