I started using these when they were recommended to me by a friend, these stainless steel bottles keep water cold a long time and don't sweat. I've had them in a back pack in Disney World and never got anything else in the pack wet.
I didn't know if anyone would be interested but thought I would pass it along
Stainless Steel Vacuum Insulated Water Bottles | Hydro Flask
Travis Rosbach was fed up with reusable beverage bottles that failed on every level, from plastics that leached harmful BPA to temperature fluctuations that would make Mercury ashamed. If the hot tea he put in them didn’t scald his hands when he picked them up, then the ice-cold water he took to the beach made the bottles sweat and collect more sand than a sunbather’s bikini bottom.
So Hydro Flask® began with a challenge: to create a reusable water bottle that truly performs in any environment. It had to keep hot liquids hot and cold liquids cold. Period. It should be BPA-free, lightweight, durable, sweat-proof, freeze-proof, recyclable, and come with an unconditional lifetime warranty.
The result of a year and a half of hard work and research is our beloved Hydro Flask. They are made from 18/8 stainless steel and feature double-wall vacuum insulation that ensures the temperature of the liquid inside never mingles with the temperature of the environment outside. Your hots will stay hot for 12 hours, and your colds will stay cold for 24.
Concurrently, Rosbach launched FivePercentBack.org, a website that empowers the end users of Hydro Flasks to donate 5% of our profit to any one of a list of charities that support emergency response services, animal advocacies, social efforts, and humanitarian services. Now, while our customers were doing something good for themselves by purchasing a Hydro Flask, they could also do something good for the world around them. Don’t you just love happy endings?
They also came out with a Growler for us Brew Pub fans, they are great for bringing your favorite malty beverage out on the trails for the weekend stays cold and frosty.
