I have the 2 liter gravity works system but wanted to upgrade to the 4 liter for backpacking with a larger group. Can I just buy the 4 liter replacement bags and use the filter and hoses I already have?

Does this include with a pouch or  bag?

Asked by: Indweller
This kit only includes the two reservoirs (one for clean water, one for dirty water). It does not include an additional storage bag.
