Enjoy easy sleep when backpacking in frosty temperatures. The Marmot Phase 30 sleeping bag's ultralight fabric and water-resistant down and baffled construction make it the ultimate dream factory.
The Marmot Phase 30 is an ultralight mummy style sleeping bag featuring 850+ fill power down (RDS certified and treated with PFC free Down Defender to improve water resistance), a full length zipper, a well designed, effective hood and lots of loft helped by the Pertex Quantum GL shell fabric.
If you are looking for a seriously light 2/3 season down sleeping bag with a small pack size then the Marmot Phase 30bags certainly tick the boxes. Marmot's use of ripstop Pertex Quantum GL fabric, which is one of the lightest available, allows the down to loft with ease whilst helping the bag to compress to a tiny pack size of under 3 litres with it's included stuff sack. With a compression bag you'd get it even smaller which is amazing for a bag rated to this temperature.
The Phase sleeping bags don't have neck baffles but they do have one of the best designed hoods we've tried which really helps to keep you felling toasty on a frosty night.
The Phase 30 uses Marmot's hydrophobic Down Defender to help the down to stay dry for longer, loft better when damp and dry faster than standard untreated down.
