RabAscent 300 Sleeping Bag: 35 Degree Down

Snooze in supreme comfort.

The Rab Ascent 300 Sleeping Bag provides cozy-warmth and compact carrying for nights spent under starry skies in the backcountry. Rated down to 35-degrees Fahrenheit (European Lower Limit), this down-filled bag is ideal for three-season camping. 650-fill European duck down promotes exceptional warmth-to-weight, meaning it'll keep you toasty without taking up tons of precious pack space.

The goose down features a hydrophobic coating that repels moisture from compromising its heat-trapping loft. Plus, Pertex Microlight fabric repels dewy condensation and built-up perspiration from seeping through and dampening the lofty down clusters. Other important features include a wider mummy shape for extra roominess, as well as zip-in compatibility with other Ascent bags when you're camping with your significant other.

Hand Filled in Derbyshire

Sleeping bags are firmly where we started and they remain a core part of our range to this day. Back in the 1970's when Rab Carrington was making sleeping bags in Patagonia, he probably didn't imagine that 40 years later sleeping bags with his name on them would be used all over the world in some of the most beautiful yet hostile environments.

To this day, we hand-fill our down insulated sleeping bags at our factory in Derbyshire, UK. This allows us to know for definite that, by the time our bags reach our customers, they have never been compressed or stored in a way which could be harmful for the down inside. By filling the bags in house, we can be completely sure that every down sleeping bag that leaves our factory will arrive to our customers in the best possible condition.
