The 365 Sleeping Bag is truly the bag for all seasons, with its multi-layered design, water-resistant Aquatexx® outer, and Q7 hollow fibre filling ensuring peak performance through the most testing of conditions. A removable, reversible, zip-in liner allows the 365 Sleeping Bag to be transformed from 5-season to 3-season, and offers the user the choice of soft fleece or smooth polyester as the inner lining, making this the ultimate Spring, Summer, Autumn and Winter bag – all rolled into one! Heavy-duty 10mm quick-release zips allow for a swift exit should you need to quickly leave the bag to attend to a bite, and these feature internal and external baffles running the complete length of each zip to reduce heat loss and stop cold air penetrating these areas. The 365 is designed to be used with standard-sized beds such as our Levelite and RLX Beds, fixing securely to the bed by the way of elasticated head-and-foot hoods, and dual fixing straps around the middle, ensuring a perfect fit with zero movement, which aids the zips in working efficiently and stops the bag from moving with you should you turn in bed.
