I want to sleep as soundly as a koala, who sleeps for more than 18 hours a day... With that wish in mind, we created pajamas that let you feel like a koala. The striped fabric depicts a koala relaxing on a eucalyptus tree. The 100% cotton double gauze fabric becomes softer and more comfortable the more you wash it, making it light to wear. You can relax whether you're asleep or awake.
