Free: Contests & Raffles.
I don't have hands on experience with one yet, but after all my research into public reviews and forum posts here and other hunting sites; my next back country tent will most likely be a Seek Outside. https://seekoutside.com/ FWIW tagging along for more input as well.
Ive been running a Northwest Territory 2 person tent that was manufactured sometime in the late 80's. Its starting to get thin in some spots, but the zippers somehow still work. I bought a smaller MSR hoop tent this year for when Im not with the wife. You just need to protect yourself from the elements, let your sleeping pad and bag do the heavy lifting of keeping you warm. Get whatever you want to feel comfortable, but you dont need to go crazy to make an extended hunt happen. Dont be a bigger wuss than the homeless.
