4 Season Sleeping Bags

Our 4 Season Sleeping Bags are built for colder nights and extended-season camping. With higher insulation and improved heat retention, they’re ideal for winter-ready use, chilly campsites and early or late season touring.

If you’re mainly camping in warmer weather, you may prefer our 3 season sleeping bags or 1 or 2 season sleeping bags.

A 4 season sleeping bag is designed for colder conditions where warmth matters most. They’re ideal for winter camping, late-season touring, or anyone who tends to feel cold during the night.

Warmth-focused design

Many cold-weather sleeping bags use a mummy shape because it helps reduce heat loss and keeps insulation closer to the body. If staying warm is your priority, explore our mummy shaped sleeping bags.

Ground insulation makes a big difference

Cold ground can reduce warmth fast, so it’s worth pairing a 4 season sleeping bag with a self inflating camping mattress or an insulated camping mat.

Want something lighter?

If most of your camping is spring through autumn, our 3 season sleeping bags often offer a better balance of warmth and pack size.
