Minimal weight, maximum warmth.
Prime for adventure races and minimalist backpacking trips, the Rab Infinity 300 Sleeping Bag delivers exceptional warmth-to-weight with its high-loft down insulation and lightweight construction. Rated to 28 degrees Fahrenheit, the Infinity 300 is ideal for three-season camping and milder winter conditions. Ultra-light Pertex Quantum GL fabric provides breathable comfort while blocking chilly breezes from stealing precious body heat. Plus, its DWR finish keeps morning condensation and light moisture from seeping through.
The tapered mummy shape wraps you in a cocoon of wondrous warmth when you're hunkering down for a restful night's sleep in the backcountry. 850-fill European goose down traps fiery body heat while easily compacting for efficient storage and transport in your pack. This down insulation features a hydrophobic finish that prevents built-up condensation and outside moisture from compromising its heat-trapping loft. As if that's not enough, trapezoidal vertical baffles use Flowgate technology to keep down from migrating and subsequently causing cold spots. All of these features make the Infinity 300 incredibly warm, without excess weight or bulk when you're moving fast through the wilderness.

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.
