I wish someone made a tree stand pack that is designed to be carried on your tree stand and has no padding or other things designed for carrying on your back which just adds weight. it needs non padded thin straps just enough to get on your back to climb the tree and that's it. Every quality pack I find weight pounds before you even put the first item in them due to all the fancy straps and padding in the back of them to make them comfortable to carry.
It seems many of the really good ideas on this thread suffer from being very niche--at least in this case there are plenty of tree stand hunters out there and "mobile hunting" is the latest rage, so seems it is "on market" with some potential for sales volume. I've been toying with this same thing, maybe a little different, but I've gone so far as to make some drawings, etc to maybe make one myself.
So far the tree stand packs I have seen marketed for this purpose don't accomplish what I'm looking for--so far all I have seen is packs that have features to deal with a stand or sticks--I'm looking for a bag that is designed from the ground up to fit AROUND a stand and sticks, since it's the STAND that really is the backpack. To me something like this solves two problems--1) securely carrying sticks in a way that doesn't catch on brush, and 2) allowing you to carry all your other gear that securely attaches to the stand for transport in a way that is quiet, contained and as snag-free as possible. Currently the best I've found is a big-ish hip pack that I simply strap around my sticks and bungee in place, but it's not really big enough if I am carrying much warm clothing and I think a dedicated pack purpose-built would work significantly better.
easy to criticize from afar but having used most of the popular systems out there for carrying stand/sticks, I think none are very good. Even the LWCG sticks that attach directly to the stand I think are the worst, because the offsets and steps protrude well-outside the sillouette of the stand and are perfectly positioned outside your shoulders to catch on brush as you duck past. The vertical carry like on the old lone wolf sticks/stand is great until you duck under a low branch, and the steps all catch on the branch above your head--doubly so if the staggered stack of the sticks is angled up to best grab branches or you have the sticks too high! I think this "pack" should double as a way to secure your sticks together and to the stand, as well as carry warm gear and essentials, then come up the tree with you and secure around the tree while in the stand.
My idea came to me while on a canoe trip--I have a canoe bag that folds over a thwart and each side has a separate bag that secures to the other side under the thwart with velcro, and has zippered compartments on both sides that hang down to the floor of the canoe, as well as some external pockets and a cupholder on the side toward you--great place to keep rain gear, sunscreen, food and beves, fishing lures or pliers, etc handy and secure, and it comes off in a second and carries over your shoulder with a strap for portages.
Borrowing from the canoe bag, I think the basis of this pack would be to fold around a set of sticks to hold them together when stacked, and buckle shut to secure them together quietly. This might have an extremely thin layer of padding to cushion the sticks against the stand mainly for sound, but aside from this no padding at all would be needed because it never really touches your body. A zippered bag along the length of either or both sides of the sticks, combined with a few zip/mesh pockets or dividers, could be pretty low-profile and hold your gear and sticks together as one unit--sort of a cylinder in two lengthwise halves, with the sticks sandwiched in the middle. This whole unit would then buckle tightly to the back of the stand and would secure your sticks and your gear to the stand for carrying, while you carry your stand using the standard backpack straps. You get to the tree, take the pack/sticks off, unbuckle the sticks and get rigged to climb, put the stand on to climb as normal and secure the pack and your bow/gun to your haul-line, and head up. When you are rigged, the pack hauls up and then gets strapped around the tree in front of you giving you easy storage and access to your gear. I think perhaps a double-pouch size designed to attach to a stand vertically for 3-step sticks, as well as a version for 2-step sticks that could be attached to the stand horizontally and allow the seat to fold up, would both be useful.
