Bee, how big is your pack? If you're using a Nalgene bottle, the GSI and Olicamp cups add almost no bulk unless the pocket/pouch/space you are using for your bottle is VERY tight.

Baring that, an emptied coffee can, that you pack some or all of your gear into? Or even a soup can. It doesn't have to be sexy, it just has to work.

BTW, I've got the same problem as duckear with the image.
