SunFriend Sunlight Monitor
Here's an ingenious way of monitoring your sun exposure! We all need sunlight-induced Vitamin D to stay healthy, but we don't want to burn. This wristband tells you when you've reached maximum sunlight for your skin type. Simply set your numerical sensitivity level; when the lights flash, it's time for sunscreen. There's even a button that checks the day's UV index! No worries about reflective radiation off snow and water, or changing locations; the SunFriend senses the UV-A and UV-B and keeps track for you! Choose bright blue or gray; both have yellow band and accents. Adjustable size.
