Based on the highly successful Big Snooze Sleeping bag, the Big Snooze Smooth Sleeping bag is our lightest sleeping bag, weighing in at a mere 3kg without compromising the warmth that the sleeping bag has to offer. It has been lined with a super-soft and smooth polyester material that allows for free movement when inside the bag and features heavy-duty 10mm quick-release zips on both sides. There are secure elasticated fixings at both head and foot ends and a bed fixing strap which aids with reducing movement and prevents getting snagged up inside your sleeping bag.
