Frequently Asked questions

What is the difference between a backpacking and camping sleeping bag?

Camping is usually vehicle-based. As a result, camping sleeping bags are usually heavier and much less packable than backpacking bags. Because they don’t need to be as light or pack down as small as backpacking bags, the materials used to make these sleeping bags can sometimes be heavier. 

How much should a backpacking sleeping bag weigh? Is there a max weight?

This depends on the user’s tolerance for weight and the conditions the sleeping bag will be used in. For ‘normal’ early summer- early autumn use, a reasonable maximum would be 2.5lbs / 1100g, but lower is always better. Compressed volume is also a key factor. 

What's the best way to compress a sleeping bag for backpacking? Roll, fold, stuff?

A synthetic-insulated sleeping bag should always be stuffed; rolling the bag means the direction of compression is always the same. This negatively affects the insulation in the footbox (at the center of the of the roll) most. Down bags can be stuffed or rolled; stuffing is usually better.

What's the best way to pack/attach a sleeping bag for backpacking?

We would not recommend attaching a sleeping bag to the outside of a backpack - it could be damaged by sharp branches/soaked by rain. A compression sack reduces the packed volume of a sleeping bag, but if the bag is still too bulky, replacing it with a more compact bag is the best option.
