Shopper Does this fit the SoftBottle?
KELSEY L Yes, this does work with the SoftBottle (both 0.5L and 1.0L).
JASON M I have used it on traditional type platypus with small opening, but the soft bottles seem to have the same size cap. Looks like it would work to me.
LORAINE Z Yes it does. It also fits the 1 liter size PlusBottle. Hope this helps!
OSCAR E Yes, it does fit the soft bottle. The soft bottle with the Push-Pull cap is a great way to carry liquids with very minimal weight!
NANCY S Yes, it fits the collapse bottle. I bought one along with the newer version that has a soft plastic swivel for open and close. They are interchangeable . My push pull cap have an cover over it which is not shown here.

BEVERLY A No, they did not fit any type of water bottle
