In Japan the Haramaki or Belly Warmer has been keeping both men and women healthy and warm for well over 100 years. It's perfect on board a cold airplane or in an over air conditioned office. It also warms your entire body so you don't have to bury yourself with layers of clothing and as the haramaki is extremely compact you can easily store it in your bag and slip it on whenever you get to feeling a bit chilly. The Belly Warmer is also great in bed as many users feel that it warms and calms them down allowing for a better sleep. This special 'murmur magazine' and Papersky haramaki is made in Japan of 100% silk and we've hand stitched both logos with glow in the dark thread- so even in the dark you'll always be glowing.
