I have a few from most of the various brands.
Started with TAG BOMB in 2013 and every single bag is still going strong, packing a few animals per year with at least one elk. Only complaint is the small diameter which is intentional to help keep structure to the meat.
TAG are the lightest or thinnest I have found, Argali might come close but I haven’t used them on game yet.
KUIU have been great and I like the size options and medium zip bag. I use the medium (20”x30” ish) for elk bone in hind quarters. They cover all the meat and stop just shy of the hock. I also use these when I debone because the 20” opening is big enough to get the meat into after removing the bone and I don’t have to cut a bunch of the muscle groups apart. Construction techniques and design features are improvements over other traditional rectangle shaped bags.
Caribou are fine, rectangular shape. I find these are a courser material and tend to imprint and stick to meat on me leaving the material grid on the meat surface imprinted. Little heavier material, durability has been good and I also use these for HQ elk bags because they are sold as singles and the small is 20”x30”.
Allen backcountry. Very economical, seem like a caribou knock off, durability has been fine and they work with HQ capable size.
Black Ovis they have some neat features, little heavier material like the Caribou, good size to keep some structure with a decent opening size but can be awful tight for bigger hind quarters. No durability issues and they just work.
Argali I picked up a set and gave most to my friend as a gift but kept a few for myself. Lighter weight bags and excited to try them out. I got an appropriate size for HQs. No on game use yet
Any of these you can set a bag straight on any dirt or sand with meat in it and your meat will remain clean unlike the cheese cloth bags. Bugs cannot get through and they all cook meat well with TAG being the best due to the lightest material in my experience but I don’t think any one of the bags I listed above will make the difference in getting your meat cool. They all do what they should. I’ve had most for awhile with TAG being the longest and most well used.
