Details Rab Neutrino 400 Down Sleeping Bag - Women's The Neutrino 400 is a lightweight, low bulk women's sleeping bag suitable for fast and light winter adventures. Lightweight, high performance materials and a highly tapered design minimise bulk, and offer exceptional warmth and protection for its weight. The Neutrino 400 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, and with an adjustable drawcord around the hood you can cinch the bag around your face. he women’s specific cut is fractionally shorter than the regular bag but is filled with the same weight of down, with a narrower shoulder and marginally wider hip space for comfort and efficiency. Built with a recycled nylon lining and recycled Pertex® Quantum outer, it’s wind resistant and a little lighter on the planet too. The down is also finished with a Nikwax, fluorocarbon-free hydrophobic treatment, for coping with condensation. It has a ¾ length zip with anti-snag zip guards, a zipped internal stash pocket and comes with a waterproof roll-top compression sack for easy packing. Hand-filled in the UK, all Rab's down bags benefit from never having had their down compressed before use, maintaining the down’s loft and warmth.
