Tell Me More

The Neutrino Pro 300 embodies the Alpine spirit. Designed with a narrow mummy fit, for reduced bulk and pack size, and constructed with lightweight, high performance materials. Perfect for two season, fast and light mountain adventures, where temperatures at night can drop significantly.

The Neutrino Pro 300 is filled with 300g of 800FP, goose down is 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 and with an adjustable drawcord around the hood you can cinch the bag around your face.

The Pertex® Quantum Pro outer is made of recycled nylon and offers wind and weather resistance, ideal for coping with condensation and damp conditions on exposed bivi ledges. The down is also finished with a Nikwax, fluorocarbon-free hydrophobic treatment, resisting moisture and improving performance over extended trips in damp weather.

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.
