The Sleeping Bag Expansion Baffle is a great piece of kit if you are extending the useable range of your sleeping bag by wearing more clothes, its not uncommon to wear a down jacket inside your sleeping bag when its cold - expanding the internal volume in this way gives you ore scope.
Mountain Equipment says:
A lightweight expansion baffle providing greater internal space to our down sleeping bags.
Our Verdict
Mountain Equipment's Helium Sleeping Bag Expansion Baffle is a great innovation, Helium bags are one of Mountain Equipment's premium backpacking ranges and as such are cut for warmth rather than internal volume - with this expansion baffle you can create a bit more space easily. If you are using your Helium bag in colder conditions and want to wear more clothing the baffle may be a great option.
