Washing instructions: Machine wash at 40 degrees. Always close zippers before machine washing. Use a soap-based detergent or a small amount of mild, liquid detergent. Do not use fabric softener. We recommend tumble drying, together with tennis balls, on low heat or hanging or laid out for around one or two days. The product may also be dry cleaned. Miscellaneous: Use sleeping bag sheets and a sleeping bag cover to protect the product from dirt. Feed the sleeping bag into the compression bag instead of rolling it. In order to keep the insulating qualities of your synthetic sleeping bag in the best possible condition, it is better to air the product instead of washing it too often as the synthetic fibres' silicone treatment gradually disappears with washing. Place the sleeping bag in a large storage bag for long-term storage; do not use the compression bag.
