Lezyne's 2L Bladder is easy to clean, durable and has features you'll love. It's built with tough polyurethane for reliability and has a zip-seal closure that doesn't leak. The wide-mouth opening makes for easy filling and lets you turn the reservoir inside out for hassle-free cleaning. Plus, thanks to a very effective anti-microbial film, these reservoirs last longer than ever. It also includes a cut-to-fit drinking tube and the drip-resistant, high-flow bite valve.
