For the mountaineer looking for a lightweight, space-saving bag suitable for cold temperatures, the Neutrino 400 offers exceptional compressibility and warmth for its weight. Designed with a narrow mummy cut for a small footprint and pack size, and constructed with lightweight, high-performance materials. It's perfect for three-season adventures
.
The Women's Neutrino 400 is filled with 400g of 800FP goose down, stabilized in chevron-shaped baffles, cleverly designed to reduce the amount of fabric needed compared to traditional horizontal baffles. The trapezoidal construction of the boxwall baffles allows the down to fully expand, eliminating cold spots and maximizing warmth. Additional baffles along the zipper and around the neck reduce heat loss, and with an adjustable drawstring around the hood, you can tighten the bag around your face. The women's specific cut is slightly shorter than the regular bag but is filled with the same weight of down, with a narrower shoulder and slightly wider hip space for comfort and efficiency, and
now constructed with a recycled nylon lining and recycled Pertex® Quantum exterior, it's wind resistant and a little lighter on the planet too. The down is also finished with a Nikwax hydrophobic, fluorocarbon-free treatment to deal with condensation. It has a ¾ length zipper with snag guards, an interior zippered storage pocket, and a waterproof roll-up compression bag for easy storage
.
Hand-filled in the UK, all of our down bags benefit from the fact that their down has never been compressed prior to use, maintaining the volume and warmth of the down.
