Retailers' Descriptions

Here's what other sites are saying:

You like to get out as often as possible, but unfortunately your boss does expect you to come into work from time to time. Spend the best nights of the week in the Rab Ascent 900 0 Degree Down Sleeping Bag, and come back to work feeling rejuvenated from your time spent in nature. This bag is insulted with high-loft down that traps in your body's hard-earned heat, with trapezoidal baffles that eliminate traditional cold spots in the bag. Rab worked with Nikwax to develop a hydrophobic treatment for the down, so it resists collapse when faced with moisture. The semi-rectangular shape gives you plenty of room to sleep comfortably, without losing efficiency to empty space. Details like a stash pocket and snag-resistant zipper make this bag easy-to-use in the tent whether you remembered to bring your headlamp in or not, making your night a low-stress experience.
