If you do a lot of driving and like to keep a pick-me-up beverage at hand, this re-sealable, leakproof flask will protect your clothing and car interior from messy stains and sticky spills. Called the 2010 Best Commuter Cup after rigorous testing by the HS Institute, it is easy to drink from yet does not leak a drop – even when tipped upside down and shaken vigorously.
Sporting a handleless, slimline design that fits nicely in your car’s cup holder, the 2010 Best Commuter Cup features a dual-wall construction with vacuum insulation that ensures optimal temperature retention whilst preventing the transfer of heat or cold to the cup’s exterior – keeping your morning coffee piping hot without burning your hand.
Scoring top marks during insulation testing, the 2010 Best Commuter Cup held boiling water for two hours and only experienced a temperature decrease of 9º F – whereas lesser models lost as much as 45º F. The Commuter Cup also excelled at sealing in the cold, keeping ice cubes frozen for a full 24 hours while other models allowed ice to melt in just a few short hours.
Made from 18/8 stainless steel with a 16-oz capacity, the 2010 Best Commuter Cup measures 9.33″ high x 2.5″ in diameter and is available now from Hammacher Schlemmer for $29.95.
