Quilts. Fuzzy slippers. Candles. Hot tea. These are a few of our coziest things. But we'd argue that a good hot water bottle out-cozies them all. Especially this generously sized heart-shaped one, with its soft, handmade Merino wool cover. Pour hot water into the thermoplastic bottle, and slip it under the bedcovers a few minutes before you turn in. No matter how cold the air is, your bed will almost instantly become a sanctuary of toasty bliss, and stay that way for hours. Thrifty green goodness bonus: you'll be able to turn your heat down quite a bit. Wonderful for comforting cramps, sore muscles, and anxiety, too. Made in Germany.
