Big Sky has a new shelter "Soul 1P" coming out that looks interesting.
Unlike many of the UL tents these days, this one is truly freestanding (no stakes necessary at all, not even for the vestibule) and it looks to have great headroom too.
Comes in various models made from different fabric specs:
$99 40D "heavy" 1kg model
$149 good (weight TBD)
$199 better (weight TBD)
$399 best (795 grams)
A real double wall tent with poles lighter than most 1P trekking pole tents. And, no trekking poles required.
My only question is how will it handle wind? Those poles have to be pretty gossamer (noodly) to achieve those weights, but the x frame wedge construction is well proven as being good architecture. Thoughts???
