VectoX 42 mm Wide Mouth is compatible only with the popular BeFree water filter by Katadyn (not compatible with Sawyer filters). 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 narrow mouth 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 VectoX 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. VectoX dries quickly with the large opening.
