Criterion Expedition 1100 Goose Down Sleeping Bag


The Criterion Expedition 1100 sleeping bag would be ideal for a trip to Antarctica. With 1100-gram of Polish goose down, it has a Leeds comfort temperature rating of -40!



The Criterion Expedition 1100 sleeping bag is the ultimate winter conditions bag. Used by the British Antarctic Survey, the Expedition 1100 is a hardy goose down sleeping bag that offers a comfort rating (the one that matters) of -40c!

It’s filled with arguably the most efficient down in the world, Polish goose down with a fill power of 850.

And it’s not just the down that makes these Quantums have an amazing ‘comfort temperature rating to weight ratio’. Instead of sewing through like most coats, or having a box construction like most sleeping bags, they have a trapezoid construction which, although a complicated process, helps the heat stay in and the cold air out.

The neck baffle feels great when you’re cocooned within, stopping the warm air from escaping. Even the zip has an insulating baffle and the drawcord for the cowl hood and baffle is one simple cord.

Criterion bags have always had a Pertex Quantum shell, the shell on the Prime is a hardier Pertex at 52g/m². This down-proof material feels lovely to touch but is also super ultralight and hardwearing.
