Rab Ascent 0C / 32F Regular Sleeping Bag Left Zip

 

L.O.F.T™ construction is built with offset baffles to prevent cold spots and make the down more effective. This allows us to use less down to achieve the same warmth, creating a lighter, more packable bag.

 

Grangers Down Defend® is a bluepass approved hydrophobic down treatment that helps keep down lofted in damp conditions. It gives the down over 375x more durability than untreated down, extending the lifespan of your product. It achieves a shake test result of at least 2000 minutes for recycled down and 15000 minutes for virgin down. It also improves the fill power of the down by up to 5%, overall keeping you
warmer, for longer.

 

We are certified to the Responsible Down Standard, certified by Control Union CB-CUC-839597. The Responsible Down Standard (RDS) independently certifies down and feathers against animal welfare requirements and tracks it from farm to final product.

 

A soft, lightweight, windproof fabric with a tightly woven structure. Highly packable and protective, it's ideal for mountain activities.
