The Neutrino Pro 400 is a protective but lightweight down-filled sleeping bag primarily designed for alpine climbers, lightweight mountaineering trips and cold conditions.

Well suited to alpine climbers, our new Neutrino Pro range is designed to take you from big wall bivi ledges through to lightweight mountaineering and winter conditions. Significantly lighter than its predecessor, the Neutrino Endurance, warmth has not been compromised. In fact, careful consideration of construction and thermal efficiency has bettered its temperature ratings and lowered overall weight.

Hand filled in Derbyshire, Neutrino Pro 400 contains the highest quality 800FP ethically sourced European Goose Down. Designed to maximum warmth, the chevron shaped baffles ensure the down is held over the centre of the body and prevent down migration, while the trapezoidal chamber design eliminates cold spots.

The outer is made from the durable and water-resistant Pertex® Quantum Pro providing excellent protection in both cold and damp weather. Cut to have a ‘mummy taper’ shape and angled footbox; this bag has a low pack size and weight without compromising on warmth or comfort and still allows for movement.

The Neutrino Pro 400 has an ergonomically designed, close-fitting internal collar with a hood drawcord, as well as a 3/4 length YKK anti-snag zip with an insulating draft tube to keep out the cold. Other features include a handy internal stash pocket, dry bag compression stuff sack for transport and cotton sack for storage.
