Made from quality 18/8 grade stainless steel inside and out, this vacuum insulated bottle will keep your drinks cold for up 12hrs or hot for up to 6hrs. Using this insulation technology also prevents condensation building up on your bottle, which would cause your bag’s contents to get wet. BPA-free, the “Skinny Mini” Pastel drink bottle features a leak-proof, easy grip lid with built in carry strap.
