The 23Zero Alaska Black 900 Sleeping Bag is made for heavy-duty use with a tough water-resistant poly-cotton shell.

Don't let its tough exterior fool you though, inside is a 100% cotton flannel liner and dual layers of insulation for a cosy sleep in any environment. Zippers feature down each side and along the foot section so you can open the bag all the way or just use the zips to manage warmth retention and ventilation.

The features don't stop there though, inside is a storage pocket so you can keep valuables safe and the bag comes complete with a flannel-lined pillow. The Alaska Black 900 Sleeping bag is perfect for use in a swag or rooftop tent.
