The Marmot 2020 Phase 20 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.
Marmot have taken the Marmot Phase 20 and tailored it for ladies with a ladies size and fit plus lots more down. Marmot have added extra down into into key areas to make the bag suitable for ladies down to -12°C.
If you are looking for a seriously light 3 season down sleeping bag with a small pack size then the Marmot Phase 30 certainly tick the boxes. Marmot's use of ripstop Pertex Quantum 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 6.5 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 cold night.
The Phase 20 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.
