Frequently Asked Questions (FAQs)

1. What are rectangular sleeping bags good for?

For those who like to move around and shift positions in their sleep, a rectangular sleeping bag is the way to go. This type of bag is all about comfort, while weight and portability usually aren't a top priority.

2. Are down sleeping bags good?

DOWN VS. SYNTHETIC - Down insulation is more expensive but has a better warmth-to-weight ratio and packs down smaller. Down bags also last longer than synthetic bags if taken care of properly. Synthetic bags are often heavier and bulkier than down bags, but they tend to cost less and retain heat a bit better when wet.

3. Which sleeping bag shape is more effective?

The most thermally-efficient sleeping bag shape is the mummy. This design is wide at the shoulders with a pronounced taper to a narrow foot, reducing the amount of space – and air to be heated – within the bag.
