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.

Huh... never seen that posted anywhere before. if you've got issues with the henie-lid getting stuck, you can just cut out the center of the wilson lid to allow you to poke the henie lid out with out risk of warping the wilson... matter of fact, that'll shave some weight ;)

Good idea, Joshua. Thanks
