I have Argali, Black Ovis and Caribou. Argali is a cut above the other 2. I don’t have anything bad to say about the BO and Carbou as both are excellent bags. The Caribou and BO bags feel very similar, the argali bags are a different more breathable material. The Argali bags pack down smaller, and just have a better overall fit and finish.
Another vote for TAG bags. Used the 24x60 for moose this year they were flawless. Got them all cleaned up and taking them to Afognak for my elk in a just a couple week. If you don’t mind weight the Grizzly cotton 30x50 has been a staple for us for years. Never an issue with those either. The Grizzly synthetic bags allowed flies through to some meat though. That’s a sample size of one so take that with a grain of salt.
I’ve used Caribou for the last 5 years and they’ve been great. They’ve held 3 elk and a half dozen or so deer. In August I was gathering my gear and was one bag short and figured I left it with one of my hunting partners last hunt, so I ordered a new set of Tags from Larry.
the set is nearly a pound lighter than the Caribou bags. I ditched the stuff sack and cord locks, and vacuum packed them. Makes for a compact and light package. That said, I carried the Tag bags extensively but haven’t gotten any blood on them. Maybe these bags are bad luck?
my tag bags have been used on 18 animals in the last 5 years so far. they've held up great and are lighter weight than the other brands i've helped load. i've added a couple bags to the b.o.m.b. pack to give me options. i do have a black ovis quarter bag but don't plan on switching any time soon.
