    Vecto is a collapsible water bladder with a unique dual opening for quick, easy filling. One end has a wide opening with a slider seal while the other end, a 42 mm screw-on cap. The wide opening makes it easy to scoop water, even from a shallow, low-flow stream. No need for a separate scoop to fill this bladder. The cap and slide are tethered to the bladder so they can’t be lost.

    The bladder is made of soft-yet-tough TPU that stands up to 220 lb (100 kg) of force. It’s much easier to squeeze than most standard bladders. TPU is FDA approved and BPA free.

    Vecto 42 mm is compatible with the popular Katadin BeFree water filter. Just scoop water, seal with the slider, screw on the filter, squeeze the bladder, and voila – clean water. Simple. Or set up a gravity filter using two Vectos, a 42 mm for dirty water and a 28 mm for clean. Screw a Coupling to the BeFree to attach the 28 mm bladder. Use two different color Vectos to help identify the dirty bladder. Hang from the hole in the slider or tie a cord through the hole for a larger loop.


    The wide opening makes Vecto very easy to clean. No special brushes or tablets needed. Get your whole hand in there with a soapy sponge and hot water to thoroughly clean the inside. Standard bladders can take a week to dry. Vecto dries quickly with the large opening.
