For those who use the Steripen Adventurer, I'm curious as to what container you are using during sterilization? I've read some of the following ideas:
1) Nalgene widemouth hard bottle
2) Nalgene widemouth soft side canteen
3) Cooking pot -> once treated pour into platypus
4) I picked up a Platypus Bigzip 2L hydration bladder (the new SL model) with the zipper on top and new locking mechanism. At 4 ounces this may work.
Anyone using something other than these?
