+1 For TAG bags. I have 4 of the larger moose size quarter bags, and then a grip of smaller boned out meat bags. Have had the same set since 2016, carrying multiple animals each year. Still going strong, and wash...pretty clean each time.
I had a chance to try the zipped KUIU bags on an Elk hunt in Wyoming this year. Gotta say for back straps and tenderloins they were pretty nice. But I will keep using my TAG bags until they give out in another decade, then will buy replacements.
