And when there is snow an ice fishing sled work great for getting the gear in and Bambi's daddy out. A sled can also help float gear and game into or out of swampy or marshy areas....
I hunted with fixed stands and climbers for years until I discovered saddle hunting. I have a few models that i use for different occasions. I’ve spent a few years developing my system, it’s not perfect but it works well for me and it looks like just what your looking for. Look up the New Tribe Kestrel. It’s a very minimal lightweight saddle that you wear into your tree. There are 100 different ways us saddle hunters climb trees, but I personally use tree spikes and special equipment to rappel down. It’s the ultimate lightweight hunting system that is safer and more comfortable than any climber or fixed stand.
