Get cuddly with the Crystal sleeping bag ($149) from Big Agnes. This 30-degree, comfort sack pairs PrimaLoft with 650 Fill Goose Down for a lightweight and packable bag that stays warm even when wet. Weight won’t be a problem either. At just 2 lb. 10oz, this thing’s lighter than canned soup. The Crystal also features an integrated pad sleeve, ensuring that sleeper(s) never roll off the cushion—even after a good party. Weight: 2lb 10oz.
