Frequently Asked Questions

AI
Generally, no. Because they have more internal space, your body has to heat a larger volume of air, which can lead to more heat loss than the snug fit of a mummy bag.
Prioritize higher fill weights, flannel or synthetic linings for warmth, and a reliable temperature rating that matches your expected environment.
Many synthetic bags are machine washable, but always check the manufacturer's label first. Use a mild detergent and avoid high heat in the dryer to protect the insulation.
