A new Camelbak bottle will keep your drinks cold for 24 hours or hot for six hours. The Chute Stainless Vacuum Insulated, ($99.90/1.2l: $79.79/0.6l) is a double-walled stainless steel vacuum sealed bottle with a rapid-flow spout, half-turn cap and two-finger carry handle and cap tether.

As well as insulation, the double walled design eliminates condensation, which helps keep packs dry and clean.

Commenting on the new bottle, Camelbak chief marketing officer, Chris Strain said: “We are committed to reducing the amount of disposable bottles used. Chute insulated allows cold water to be enjoyed all day long, on a hike or after leaving the bottle in a hot car.”
