Hands-free hydration systems are convenient, effective, and make long hikes and extended missions much more comfortable. The only problem is that empty bladders are extremely hard to clean. Sponges, let alone hands, cannot fit into their small water ports which can lead to foul tasting water and potential health risks. Luckily the Max Gear Cleaning Tablets from CamelBak are here to help. Each tablet is composed of a chlorine dioxide formula that quickly dissolves to remove nasty buildups that can cause bad taste and breed deadly bacteria. The tablets are safe and can clean up to a 100-ounce reservoir. Tablets are specifically designed for CamelBak reservoirs and water bottles.
