I bought a Hennessy a few years back, thinking it would be great for elk hunting. for me I found it had pros and cons.
Easy to set up. compact, fairly light. Thats about it as far as pro's, IMO.
Getting in and out of a sleeping bag inside it is like tryint to get toothpaste back inthe tube. No matter how tight I strung it, I could not get a good nights sleep in it. If you are a back sleeper, you're probably fine, but I sleep on my side, and it was very uncomfortable. I woke up tired, stiff and sore.
If I had to get up inth night to pee, repeat the process of getting in and out of the bag.
Its been collecting dust in my gear closet ever since. If anyone wants it, I'll give you a good deal on it.
I've since switchedto a Kifaru Paratipi. Lighter, more room, bombproof, and has a wood stove if it gets cold.
