Reporting from the International Home + Housewares show in Chi-town, we recently showed you Alex Bottle's new stainless steel bottle and Kor's Vida and Delta models. All three are consumer products, things we can tote to the office or gym.

The next level up in portable hydration is the higher-capacity, wearable, durable and flexible bladders worn by hikers, long-distance runners and mountain bikers. CamelBak is perhaps the best-known of these, producing models like the Lobo and M.U.L.E. seen below, which essentially double as backpacks and have "Big Bite Valves" that control the flow of water. The bags are tough, slim to allow freedom of motion, and have capacities of up to 100 ounces/3 liters.

At the top of the toughness chain we have "battlefield hydration" products, essentially simplified and ruggedized versions of the wearable bladder intended for military use. The no-nonsense design of these won't win you any style contests, but they are made to be a good deal tougher and in some cases, resistant to chemical attack.

MilitaryTimes.com recently conducted a shootout-style durability test where they dropped concrete bags on the toughest of the tough, and while none of the contenders survived unscathed, Source's Max CBRN model was the winner.

The 9-minute, continuous video of the testing could use some editing, and if you're curious about the products we recommend scanning through it rather than sitting through the whole thing:
