Got a Sawyer mini filter on the way and I am buying a new Platypus 3L big zip hydration bag. I am wanting to connect the filter to the bladder line. Is there a specific attachment from Sawyer that I need to purchase to make it work or can the filter be attached right into the bladder line? I have only had experience with a Seychelle in line filter that I had attached to my old camel bag bladder and it required specific attachments to the water line from the bladder.
