TAG Bags are all I use. They are strong, lightweight, and easy to clean. If you're meat doesn't get a good crust before you put it into the bags and they get bloody, you can wash them out, hang them up, and in an hour or so, they'll be dry. Its easy to carry all of the bags you need in your backpack/daypack so that you will have them when you need them.
I have both the Moose/Caribou bags and have been using them for the last 7-8 years.
Good luck,
