check out this recent review of the SlingFin HardShell tent from Outdoor Gear Lab.
The SlingFin HardShell tent is the equivalent of Air Force One for mountain climbers and polar explorers. Its innovative design and premium materials make the tent reasonably lightweight (12 lb. 4 oz. with carbon poles), easy to setup, and castle strong. It's like a portable luxury suite for the world's most heinous conditions.
