Our friends at Polar Bottle did it again! They designed another fantastic water bottle to meet our TrailblazerGirl needs. Their new ThermaLuxe vacuum insulated water bottle is perfect for both cold and hot liquids. This stainless steel bottle has a dual-wall to keep our cold liquids cold for more than 24 hours and hot liquids hot for at least 5 hours (yes, we tested it, and it kept our tea nice and toasty!). No worries about spills or leaks with their special silicone gasket and contoured cap in this 21 oz bottle.
