Cotton Sleeping Bag Liner Waterproof

Does the Cotton Sleeping Bag Liner absorb wetness or just block it?

It's a waterproof barrier, not an absorbent product. Two layers of cotton jersey are bonded with a waterproof polyurethane membrane, so accidents are contained on top of the liner rather than soaked into it; the sleeping bag underneath stays completely dry.

What size sleeping bag liner do I need?

Choose Kids (170cm x 70cm) for a standard child sleeping bag, or the newly added Adult size (Length 185cm x Width 80cm) for teens and adults using a full-size sleeping bag.

Can adults use the Cotton Sleeping Bag Liner?

Yes, an Adult size (185cm x 80cm) has been added to the range, currently available in Navy, so older kids, teens and adults can use the same waterproof protection as the original Kids size.

Is the liner suitable for camping, not just bedwetting protection?

Yes. Because it's waterproof on both sides, it also stops ground moisture from reaching the sleeper, making it useful for camping and outdoor sleepovers as well as night-time toilet training.

How do I wash it?

Wash separately before first use to soften the fabric, then cold or warm machine wash only. Turn inside out and spin again if water is trapped after washing, and line dry or tumble dry on low. Avoid ironing, dry cleaning, bleach and fabric softener.

Is it certified safe and sustainable?

Yes, the Cotton Sleeping Bag Liner is third-party tested and Green Leaf certified as environmentally sustainable and non-toxic.

What is a sleeping bag liner for?

A sleeping bag liner adds a protective layer inside a sleeping bag. Some add warmth, while waterproof versions like Brolly's protect against wet accidents, sweat or ground moisture reaching the sleeper.

Do sleeping bag liners come in adult sizes?

Yes, though not every brand offers them. Brolly's Cotton Sleeping Bag Liner now comes in an Adult size (185cm x 80cm) as well as the original Kids size (170cm x 70cm).

Are waterproof sleeping bag liners the same as absorbent bedwetting products?

No, a waterproof liner blocks moisture from passing through it, while absorbent products soak moisture up. Brolly's Cotton Sleeping Bag Liner is a waterproof barrier, not an absorbent pad.
