    Great invention

    The liner is great with this sleeping bag inside adding extra warm. It also can be cleaned after you go camping so that your sleeping bag is still brand new after you use it.

    Great liner

    Cotton is breathable and easy to machine wash. Keeps the sleeping bag clean from body, odors, sweat and exfoliating skin.

    Love the sheets just wish they were bigger

    Sheets are soft until you get sand on them and then they feel like sand paper; hazards of beach camping 😳

    We use two xl 30” therm-a-rest pads and the sheet doesn’t span the 60” so it’s made it hard for us to sleep inside the bag.

    Perfect for the mammoth sleeping bag

    I used this with the mammoth sleeping bag and it was perfect. It makes it so much easier to clean the camping gear and keeps the inside of our huge sleeping bag nice & clean 🙌🏽
