Warm sheets and a snug couch, the old-fashioned way

This classic 2 L hot water bottle is for anyone who runs cold at night or likes to curl up under a blanket with a book. It needs no power: just fill it with hot water from the tap or kettle, screw on the cap, and slip it into its soft cable-knit cover. The clear bottle shows the water level as you fill, so there's no guesswork. Stay snug in bed or on the sofa: tuck it under the covers before bed or keep it on your lap while you watch TV.

Why you'll love it

  • How it works: Just fill it with hot water. No power or charging needed.
  • Easy to fill: The clear bottle and wide opening let you see the water level as you pour.
  • Secure screw cap: Closes firmly, with a leak-resistant design.
  • Soft cable-knit cover: A cozy knit with a ribbed collar that feels nice to hold.
  • Removable cover: Slips off the bottle easily and goes right back on.

Perfect for: warming up your bed on chilly nights, reading or watching TV, keeping your hands or feet warm at your desk, and cozy evenings on the sofa.
