Neutrino 400 Long Wide Sleeping Bag

For the alpinist looking for a lightweight, low bulk bag suitable for cold temperatures, the Neutrino 400 LW offers exceptional packability and warmth for its weight. Designed with a wider and longer mummy fit and constructed with lightweight, high performance materials. It’s good for three season mountain outings. The Neutrino 400 LW is filled with 400g of 800FP, goose down, stabilised in chevron shaped baffles, cleverly designed to reduce the amount of fabric needed compared to traditional horizontal baffles. The trapezoid boxwall baffle construction allows the down to fully loft, eliminates cold spots, and maximises warmth. Additional baffles along the length of the zip and around the neck decrease heat loss - with an adjustable drawcord around the hood you can cinch the bag around your face.
