Best winter sleeping bags for adults that will keep you warm at night

It could be argued that the only time it’s acceptable to want to look like a sausage roll is tucked into a sleeping bag outside. Fit Nation’s blue polyester Viking Trek sleeping bag manages the makeover admirably with a corded hood and neck to allow you to winter through all weather.

And yes, we really mean through all weathers: this baby is built to keep you warm through anything, even if it’s snowing outside. Simply slip in, pull the anti-catch zipper and head out inside, knowing you’re protected from the elements. The carry bag is also waterproof, so don’t worry if it rains when you clip your sleeping bag to your backpack. A huge amount of warmth for minimal carrying weight – this weighs just 3.17 lbs.
