The Camel Back 100 oz. BFM with Improved Patrol Pack. This is proving to be a great item for combat field medics. We sampled the competition but their claims failed to meet muster. Camel-Bak has dominated from the beginning of the hydration revolution and they are still leading the pack with a fairly comfortable margin. We needed a product that would match Mil-Spec for life span durability and they are continuing to outpace competitors. The bite valve on Camel-Bak Military grade systems is hands down the best for field work. The options and styles make Camel-Bak a solid choice for tactical hands free hydration. There is a broad selection of styles to fit individual needs and missions. The small patrol Packs are great for security operators and all styles are available in Olive, Black, Camo, Desert, Coyote, and Digital Camo. Rangeresqe is recommending choosing a durable insert of at least 70 oz. for use with assault vests and packs, and spares 70 oz or larger to be used for storage blivets inside a larger rucksack.
