Our pure merino lambswool covers are designed to keep your bottle toasty all night long and are perfect for slipping under the duvet, savouring a luxurious morning lie-in, or packing for a weekend away. Gently felted for extra softness and natural insulation, these me-time musts keep your hot water bottle warm for much longer than synthetic low-quality alternatives. Made from 100% lambswool, they’re a timeless, sustainable, and a true winter companion to return to year after year.
