Inner linings – Fine nylon or polyester are the most common materials used for lining sleeping bags. Flannel or cotton are also popular for sleeping bag linings, although lightweight and breathable, cotton traps moisture so isn’t recommended for cold conditions.
Compression Sack – Because they’re larger than single sleeping bags, double sleeping bags can be quite cumbersome to pack away. However, a compression sack will make packing easier and reduce the size of the bag for better storage.
Outer fabrics – Outer shells are commonly made of nylon – ripstop is popular as it is highly durable. Dryloft is a water-resistant, breathable fabric that is often used for sleeping bags.
Two-sided zips – Having zips on either side of your double sleeping bag will help ensure that you don’t disturb your partner should you need to get up in the night.
Inner pockets – A couple of inner pockets near the top of your double sleeping bag are really handy for safely storing valuables such as wallets and phones.
Hood – Much of your body heat is lost through your head, so a shaped hood is a great way to keep in heat. Many of our double sleeping bags come with a cosy half-moon hood.
