Mountain Equipment's Helium 250 sleeping bag is from their Helium series of bags which hit a sweetspot for trekking and backpacking, very technical with high warmth to weight ratios they are many hikers 'goto' bag.

Mountain Equipment says:

Weighing less than most bottles of water and packing down equally small, this is the perfect bag for the dedicated warm weather backpacker looking to lighten their load.

Our Verdict

Mountain Equipment's Helium 250 Down Sleeping Bag is part of their Helium range which are highly technical, accomplished sleeping bags for backpacking and trekking. They use 700 Fill Power down and a new baffle construction technique to achieve some excellent warmth to weight ratio figures. 706grams for a +2C bag is a good ratio.

Design wise Mountain Equipment's sleeping bags are superb, the hood and footboxes are particularly well designed with multiple baffle sections to give them shape and structure. The Helium bags have a built in neck collar rather than an out and out shoulder baffle - this saves weight and is pretty good in use.

There's a DWR coating on the outer shell which is PFC free, this will give the bag some resilience to a damp environment. As an ultralight backpacker I think these bags are a superb choice – like buying IBM, back in the day.
