MoMA Exclusive: Richard Yu was frustrated by the standard square hot water bottle that felt limited in its use so he created the original Long Hot And Cold Water Bottle which offers both warming and cooling comfort. Thanks to an adjustable strap and hands-free design, you can rest it around your neck, strap it across your shoulder or wrap it around your stomach for soothing relief wherever needed. Made from sustainable materials, it stays warm for up to six hours using less water than a kettle as an eco-friendly and budget-conscious way to stay cozy. The Long Hot And Cold Water Bottle measures 32l x 4.75"w with a strap measuring 40l x 1"w.
