The improved version of the Big Zip by Platypus is designed with a modified form. This gives the hydration system a 50% higher flow rate which makes drinking easier.
The sophisticated SlideLock closure can be pushed off in both directions and releases the zip opening. This makes fast filling and resealing possible. The quick release at the opening allows a one-handed filling without problems. Thanks to the semi-rigid partition wall, the bag stays better open thus shortening the drying time.
