Keep your beverages cold all day without a cooler (or hot without a microwave!) Our double-wall vacuum insulated stainless steel bottles prevent outside temperatures from affecting the inside beverage temperature so your drink stays just the way you like it – all day long. This convenient size fits perfectly in most cup holders and backpack pockets. Great for everyday adventures or outdoor activities like hiking, camping, biking, sports, picnics, and more. Drink the way you want with easy, controlled one-handed drinking. Chug or straw? Your choice. You get both! Note: For maximum flow, please ensure the straw lid is fully extended.
