Smarty pants/Windy saddle

SküllheadWilderness Seems a cool way to secrete a pump if you don't want to carry it elsewhere.

I've got a better idea:
Why can't someone invent a mini canister thing that isn't use-once-only? Like a refillable compressed-air canister that you can use with a proper big bastard pump at home, to fill up and take with you. I just thought of it the other day. (c) copyright 2007 me me me.
