Made by HydraPak, the OSABrands Elite Classic bladder uses the same high-spec materials and parts as HydraPak-branded bladders, simplified to deliver greater value-for-money.
The OSABrands Bladder has a generous opening with a slide-off sealer for easy filling and cleaning. The 91.5 cm flexible hose provides enough length to ensure the Surge Valve is always where you need it, regardless of where the bladder is positioned in your pack.
