Midnight Navy Merino Wool 2 Litre Hot Water Bottle

Regular price £45.00
Tax included.

Deep, timeless and quietly luxurious, our Midnight Navy Merino Wool Hot Water Bottle is made for slow evenings and properly cosy nights. The rich, inky-blue colour feels sophisticated without being formal, while the softly mottled Merino wool adds warmth, depth and natural texture.

Each cover is handmade in Wiltshire and carefully constructed to help keep your bottle warmer for longer. Its gentle creases, subtle fibre variations and slightly individual shape reflect the character of a product made by hand, not an overly perfected factory finish.

Complete with a premium natural-rubber hot water bottle, it is a comforting everyday essential made to look just as good left on the bed or sofa.

Why you’ll love it:

  • Premium Merino wool cover

  • Handmade in Wiltshire

  • Rich, sophisticated midnight navy

  • Carefully layered for lasting warmth

  • Naturally individual texture and finish

  • Natural-rubber hot water bottle included
