Buying Guide

You’ll be as snug as a bug in a rug, even in your compact and lightweight sleeping bag with the huge range of models available for hiking, travelling and trekking in our range.

We’ve got both down and synthetic bags in sizes that will suit everyone from kids to tall adults, from brands such as Black Wolf, Sea to Summit, Caribee, and Roman – so you’ll be able to find the perfect model for whatever fast and light adventure you’re planning. 

Down Filled Sleeping Bags for Hiking

The primary benefit of a down sleeping bag over a synthetic bag is that they have a much better warmth to weight ratio. What this means is that a down bag that shares the same temperature rating of its synthetic counterpart will be significantly lighter weight.

Secondly, down is far more compressible than synthetic fill so not only will you be saving on weight for the same warmth, you'll also be saving on space in your rucksack.

If weight and packed size are your primary concern, a down bag is a good investment.

Synthetic Filled Sleeping Bags for Hiking

A good quality synthetic filled sleeping bag offers excellent insulation without the hefty price tag. Apart from the price, synthetic bags have a couple of benefits over a down filled sleeping bag.

Firstly, they are much easy to care for than their down counterparts. A synthetic bag can be washed in a washing machine's gentle cycle without fear of damaging the bag. The second benefit is that, when wet, a down filled bag loses all thermal properties whereas a synthetic filled bag continues to provide some insulation. So if your activity involved a lot of water - think canyoning - then a synthetic bag may be the best choice.
