17.6 ounces on my scale, which seems pretty accurate.
I will check on availability, could produce them tomorrow if need be, but realistically, we are working through orders and to be conservative I would say after the new year for shipping. We can probably pre-order but I need to get Angie's sign off. I can get exact times by the end of the week.
I like the nest as well, in fact if going to canyon country where alcoves are plentiful, the nest is all you really need in fair weather. I will attempt to get more photo's in the next few days. I suspect it could integrate in with our breakaway tarp vestibule as well, but I need to confirm.
