The Cotton Sleeping Bag Liner is built from two layers of 100% cotton jersey, bonded together with a thin waterproof polyurethane layer to form a single piece of fabric with the weight and feel of a flannelette sheet.
Because both sides are waterproof, the liner protects the sleeping bag itself if a wet accident happens overnight, or if the sleeper wraps themselves up in it. It also blocks ground moisture from reaching the sleeper, which makes it just as useful on a camping mat as it is at a sleepover.
Sizing now covers Kids (170cm x 70cm, with a side opening for easy access) and Adult (185cm x 80cm), so older kids, teens and adults can get the same protection inside their own standard sleeping bag. Every liner is third-party tested and Green Leaf certified as environmentally sustainable and non-toxic. Read more about the test and program by clicking here

Composition:
Two layers of 100% cotton jersey with a thin laminated polyurethane layer for waterproofing.
Care instructions:
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.
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.
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.
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.
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.
Yes, the Cotton Sleeping Bag Liner is third-party tested and Green Leaf certified as environmentally sustainable and non-toxic.
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.
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).
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.

Kept the outside dry when wet inside
Great product, works well.
Hi Kate, Thanks so much for sharing your experience with us.
Fantastic! Grandson used while away camping. The liner was comfortable and best of all it did stop wetness from seeping into his sleeping bag. Easy to wash the liner and it dried quickly. Everyone happy!
