The bladder capacity is up to 2L with 1L and 1.5L markers if a lower amount of fluid is required. The bladder is designed with a large opening allowing easier access for filling and cleaning. We recommend regular cleaning and sterilising. Replacement bladders can be purchased seperately from your local retailer or via www.inov-8.com. The H2Orizontal hydration system concept, design and shape are registered and patent pending.

The hydration system uses Source™ components with anti-microbial technology which blocks bacteria growth on the tube and reservoir. The diagram shows how to easily fill and insert the bladder into the pack which can also be filled in situ

^{Only compatible with the Race Pro™ 4, Race Pro™ 12, Race Pro™ 18, Race Pro™ 22 and Race Pro™ 30.}
