Neutrino Pro 500 Ultralight Down Sleeping Bag

About the Rab Neutrino Pro 500

With over 30 years of experience, Rab sleeping bags are built on tried and tested designs; crafted using the highest quality fabrics with an attention to detail that makes them a trusted name in outdoor equipment. Each Rab sleeping bag is designed, hand-filled, stitched and finished in Derbyshire UK.

The Neutrino Pro 500 down sleeping bag delivers a compact and ultralight design with a host of technical features for climbers and mountaineers looking to keep their gear carry to a minimum.

A lightweight and highly durable Pertex® Quantum Pro shell fabric keeps the pack weight low while 500g of 800FP ethically sourced European duck down delivers highly compressible insulation for a travel-friendly pack size. Nikwax Hydrophobic Down treatment continues to insulate even when damp while maintaining loft 60 times longer than untreated down and drying 3 x faster - all without the use of PFCs. Down fill is held in trapezoidal chambers designed to eliminate cold spots while a weight-saving chevron baffle design reduces down migration and optimizes core warmth

The Neutrino series cuts out excess bulk thanks to a tapered mummy fit with an angled foot box to keep your feet warm but still allow for comfort and movement. A close-fitting adjustable neck baffle and hood provide a snug fit to seal in the warmth with a 3-quarter length YKK main zip for ease of access and a synthetic-filled baffle to help exclude draughts.

The Rab Neutrino Pro 500 gives you a high-performance sleeping bag built for alpine climbers, and lightweight mountaineering trips into the cooler months. With a pack weight of just 1005g (approx.) and compressible pack size, this bag has been optimised for the fast-moving outdoor enthusiast wanting a compact sleeping bag with a balance of low weight and 3-season comfort.
