As other have said the frames unique. It's what allows it to essentially be a day pack until you need a frame pack. Then it carries a whitetail with ease.
Popup 28 really does shrink down to normal day pack sized. That is unique amongst the usual suspects in frame pack discussions.
But it is still a frame pack, so it offers a lot more capacity for gear as well as capability for meat hauling when needed.
Pretty versatile as an all season deer pack, IMO.
That's my concern as well, the popup bag look very spartan, which some people preferred. but it would be nice of there was some organization. I'm going to adjust to this placing the pack on the side, and taking out an admin pouch with the things I need and strap it in front of me, or attach it to the belt maybe.
The other thing was my concern that the back of the bag has no padding, it make sense, but would my sticks/platform damage the pack overtime. Have you guys that carry your stand/stick see wearing down the back of the pack due to the teeth?
I'm on the path to getting the popup, but am wondering if I can find a MR guide light frame by itself would fit me better, I rather have the option of using a more efficient bag or switching out the bag based on the situation. Or not using a bag at all when I dont need to pack all that extra layers.
There are, imo, better frames for carrying heavy loads comfortably. But keep in mind the Popup 28 is unique in that it collapses to true daypack dimensions. For an all season whitetail pack, it fits the bill pretty well. I personally think the belt stinks, and have changed mine out.
I don't know what you use during a hunt, but the Popup 28 has enough isolated storage for the things I like to separate from bulk storage. As you've said, adding pouches is an option. It will just depend on your specific needs.
I don't know of any frame pack that is reinforced specifically for carrying toothy sticks and stands. It just goes with the territory. If you think it'll be an issue, find a way to cover up those sharp contact points. Usually just packing in a coat is enough of a buffer that I don't put more thought into that.
I have 3 frame packs now, and they each offer some things I like over another. I like the 28 because of it's daypack size. Hump your platform, sticks, outerwear in the load shelf, collapse it, and it hangs in the tree just like the pack the private land hunters use.
If you aren't hiking in more than a mike or two, it'll do the trick without skipping much of a beat.
