Tired of your water getting boiling-hot by the time you're halfway through your hike? Keep your beverage of choice cool for hours with the CamelBak Eddy Stainless Vacuum Insulated . 6L Water Bottle. Double-wall vacuum-insulated stainless steel is naturally BPA-free, won't leave a weird taste, and prevents condensation on the outside on the bottle, all while keeping drinks cold for multiple hours. Plus, the Big Bite valve offers easy one-handed, no-tipping-required drinking, and the integrated loop handle makes it easy to attach the bottle to your carabiner clip.
