Kurumare is a portable, battery-powered heated blanket. It warms you in seconds and features built-in snap fasteners that allow it to be adjusted to the body in a variety of positions.

Quite simply, it is the most versatile, high-tech and portable heated blanket ever designed.
What’s behind the name?
Kurumare, pronounced koo-roo-mah-reh, is a portmanteau derived from “calmare” (Italian for “soothing”) and “kurumu” (Japanese for “to snuggle up / wrap oneself in”). During testing of our portable 7.4 V heated blankets, the sensation of “soft warmth” was often described by Japanese test users as “being wrapped in the calming warmth of a bath in local hot springs”.
