I just purchased a 3L Platypus for my son for Philmont. He will be using it as a water supply when headed into a dry camp (2 on his trek). It weighs 4 oz with the hose cap/attachment, but he has no interest in the hose, and only wants to use it as a 3L container (weighs 1.7 oz empty). Where can I find a regular cap to fit this? Is it the same size as a 2L soda bottle cap?

You can probably get it from wherever you can get a Platypus reservoir. I use a cap for my 3L bladder some of the time. The soda bottle ones do not fit (they leak). Platypus sells a pack of two for $2-3.

It's silly because they ought to just be included, but it's only a couple of bucks. Not worth the time to complain, in my opinion.

EDIT: Here it is at REI just so you know what you're looking for. Listed at $2.95. http://www.rei.com/product/820772/platypus-platy-bottle-closure-cap-package-of-2

Doug I would recommend getting the Platy push/pull top in is much more versatile than the plain cap- Here

You don't need to make the string that long or that thick.

If you get the push-pull cap, be careful how you pack it. I had one get pulled open inside my daypack apparently from just being jostled inside the pack while hiking.

It's how I found out that my daypack is pretty darn waterproof and could be used as a water bucket in a pinch... :/

the caps from the large smart water bottles will fit. i've used them plenty of times with no leakage.

I always switch out my Platy push pull caps for small nalagene pill bottle caps that are stronger structurally wise and a prefect fit. You can get them at REI.
