I switch from my ultralightweight climbing stand that I use in the early season to a treelounge...at 45 lbs it is a load to carry, but I can stay 30 feet in the air all day with a few bottles of water, a baggie of trailmix, a paperback book, and an extra safety belt for when I intend on taking a nap...

I do this during all of the gun seasons...muzzleloader, modern rifle, etc.
