It's actually "almost" MYOG!
Forgive me if someone already posted this: I discovered that a plastic lid from Wilson's tennis balls can/plastic tube snaps securely on top of a 24oz Heine can. Keeps everything in place while in your pack.
It works w/or w/o the Heine lid in place. However the Heine lid does get semi-stuck inside the tennis lid – Minor inconvenience only.
