So I did a DYI to my H2O devices that meaning my shower, hydration hose/bite valve and my water filter. I had been using an old PUR Hiker filter but have started using the sawyer squeeze set up. The squeeze was good but could be better with some tweaks. First thing I noticed the bags suck but there free with the filter. So i decided to 86 the squeezing idea and when to gravity. Now the problems: I use a hydration hose in my pack with quick disconnects to fill w/o removing the bladder from my pack the Sawyer is no good for that. I bought some auto shut off disconnects to remedy the problem from http://www.usplastic.com/catalog/ite...=searchresults These parts are the same as Platapus and Katadyn but don't work with Camelbak. My video might make more sense! If you have any questions please ask. I have been using this set up with My PUR Hiker for a few years now and cant imagine using anything else. It is now light maybe not uber light but pretty darn light with the squeeze.
