Neutrino 600 Sleeping Bag: 10F Down - Women's

What Our Gearhead® Experts Are Saying:

"I brought the Rab Neutrino 600 on a late season mountaineering trip where overnight temps dropped well below the rating and the down-filled collar and draft tube made a noticeable difference in keeping warmth locked in through the coldest hours before dawn. The Pertex Quantum shell has taken some abuse from crampon spikes and rocky tent floors over two seasons and is holding up better than I expected from a shell this light."

When the objective is serious and the forecast is brutal, the sleeping bag becomes one of the most important decisions you make before leaving the trailhead. The Rab Neutrino 600 Sleeping Bag is built for exactly those nights, rated to 10°F and packed with 800-fill RDS-certified goose down treated with a Nikwax FC-free hydrophobic coating to retain loft even when conditions inside a tent get damp. At just over two pounds and stuffing down to a manageable compression sack, this is a bag that earns its weight on mountaineering objectives and serious backpacking trips where cold nights are part of the plan rather than a surprise.

The Pertex Quantum shell is woven from 20D recycled nylon with a FC-free DWR coating, giving the bag a lightweight exterior that resists abrasion and surface moisture without sacrificing the packability that makes 800-fill down worth carrying in the first place. A down-filled draft tube and collar seal off the zipper and neck opening to prevent warmth from escaping at the points where most bags lose heat first. Two-way zipper venting gives you control when temperatures swing overnight, and an internal zippered stash pocket keeps small valuables within reach without requiring you to leave the warmth of the bag to find them.
