I've had great results with "Alaska Game bags" sell them at Cabelas. Pictures is from my Antelope last year. I think I bought the bags for under $20. No need to go fancy. I like the froze ice jug idea for cooling. cooling.
I think mine are 4 years old, just washed them up after last weeks Antelope, vac sealed and they're back in my kill kit waiting to pack home a Bull.
I put that antelope in a 52qt cooler and needed 65. I wouldn't go over 100.
I like pillow cases for antelope. They're generally not in the case very long so breathability isn't a huge issue. I've used Alaska game bags and the problem with them is that flies can get on the meat if the material is stretched out. I've been thinking about ponying up for a good set of reusable game bags, but haven't done it yet.
The Allen Outfitter series bags are stretch mtl but will not open up and allow flies to get in. Very nice bag if you don't need to worry about weight or packing size. Very reasonably priced.
