These are well constructed bags that pack down small and are light to carry in your daypack. They do a great job of keeping meat clean, free of flies (and fly eggs), with good air circulation. The fabric is strong enough (although I think you should lift a full bag from the bottom), and they clean up nicely in the laundry - much better than the cotton bags that I've used for years. This "Kit" isn't quite what I would like to have when I have an elk, moose, or caribou down, though. I used this set of 6 bags for a bull moose that my daughter shot in western Alaska this year, where we were required by law to leave the meat on the bones of the four quarters. That's way more weight than I normally would pack in one load, but the four large quarter bags in this set are perfectly sized for the task. You can secure the drawstring of the bag just above the knee joint and leave the lower leg and hoof sticking out the top of the bag, or cut the lower leg off and close the bag completely, with the meat inside. If you don't plan to leave the meat on the bone, the large bags may be bigger than you need - they're bigger than I would otherwise use, if I were boning the meat completely. The two smaller bags measure 28 x 30 inches. I found these bags large enough to hold the boneless meat of the moose's neck, ribs, backstraps, tenderloins, and whatever other miscellaneous trimmings or organs you want to toss in. The problem is, that makes for another HUGE bag of meat that's difficult to lift, secure to a pack, or carry. The nearly-square proportions of the bag are too wide for normal frame packs. Even if you only partially fill the bag, the meat spreads out off both sides of your pack. If you aren't dealing with a moose, you probably won't need a "trim" bag this big. If moose is your quarry, you might want to be able to pack it in smaller, better-shaped loads. If I were to design this set, I'd substitute the two (nearly-square) 28 x 30 inch bags with four smaller bags, approximately the size of a king pillow case. That makes for a more manageable load that's better shaped for strapping onto a pack. Overall, I like these synthetic bags, and plan to use more of them in the future, as I retire my cotton pillow cases and heavier cotton laundry bags that have served me for 40 years now (with replacements over the years as necessary). I'm not thrilled with the size of these bags, though, except that the large bags are perfect for bone-in quarters of a moose or elk. I think they're bigger than necessary for caribou and smaller game, and for any animal that you intend to bone completely. I do hope to see more offerings in different sizes from this company. I'll buy more if they offer what I'm looking for, because the quality and price are both good.
