Re: What type of shelter do you use most often for backpack hunting during rifle seas
I voted 4-season tent.
Like others have posted, I too have sleep apnea. That notwithstanding, I've spent enough time in the mountains that 1) if I'm backpack hunting and 2) there's a chance for snow ..... I don't mess around with less than snow-worthy sleeping arrangements.
In my experience, a bivy just isn't my cup 'o tea. I had a very nice Integral Designs Unishelter and have used other smaller bivy's, but in the end it got sold after a couple uses. Now, I use my Integral Designs MK2 XL single-wall tent with which they did some awesome customizing for me. If it's warm weather I use my Henry Shires TarpTent "Cloudburst II" UL tent, but that's unusual for fall in the mountains....
Incidentally, I don't sleep nearly as well without my CPAP and *always* miss it (can't believe I actually said that), but I can catch 'cat-naps' here and there to make up the overnight loss(es).
