Hi Leslie. I tried it out in the garage and it was awesome. Still looking for a tarp but I suspect it will be a huge weight savings over the bivvy I normally use. Besides....I hate that bivvy. I plan to get into the whole whoopie sling club too, I can see where that would be a big weight/bulk savings.
I think I have a family reunion the weekend of the spring mahha, but maybe I will make it out to another hang somewhere.
