An insulated water bottle is a perfect traveling companion to keep you hydrated-gym, trail hikes, or office! Double-wall vacuum insulation keeps the temperature of any beverage hot for up to 12 hours and cold for up to 24 hours. These bottles are clash-proof, made from BPA-free materials, beneficial in this aspect, and usually have the added benefit of being leak-proof and sweat-proof: wearing them in the gym is an exercise in convenience! Ideal for the environmentally conscious buyer, even an insulated bottle is a much better solution than single-use plastic. Available in various sizes and designs, they are simply a practical, fashionable, and sustainable assist to everyday hydration.
