Using your Sea to Summit Reactor Fleece Mummy Sleeping Bag Liner is easy. First, unroll it inside your sleeping bag. If it's cold, zip up the shoulder zippers and adjust the drawcord at the footbox to keep the warmth in. In warm weather, leave the drawcord open for more ventilation. You can even use it on its own as a light sleeping bag. When it comes to maintenance, follow the care instructions on the label. Generally, you can machine - wash it on a gentle cycle with mild detergent. Avoid using bleach or fabric softeners as they can damage the HeiQ Fresh odour control technology. After washing, dry it on a low - heat setting. Make sure to store it in the provided storage case when not in use. This will keep it clean and protected for your next adventure.
