Neutrino Pro 500 Down Sleeping Bag (16°F)
Eliminating excess bulk with a highly tapered design and offering exceptional warmth and protection for its weight, this bag is built for fast and light mountain missions. Filled with 800FP, goose down and covered with wind and water resistant, recycled Pertex® Quantum Pro.
Performance
Activities
We recommend using this for:
- Fast & light adventures
- Mountaineering
- Trekking
The Neutrino Pro 500 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 three season, fast and light mountain adventures, where temperatures at night can drop significantly.
The Neutrino Pro 500 is filled with 500g 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 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 snow or 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.
