Stories & News Latest news Shop promotion: Brolly Sheets sleeping bag liners Get yourself a 10% discount when you buy Brolly Sheets Sleeping Bag Liners from the ERIC shop until the end of April. Available in white and navy, these liners fit inside most standard sleeping bags (170cm x 70cm) and there is a side opening to make it easy to get in and out of. The top and bottom are waterproof so if your child wets, or wraps themselves around the liner it will still protect the sleeping bag.
