Though I have a dozen tents / shelters in my camping arsenal, I've been extremely pleased with my new Sierra Designs Flash 3 UL. Like most of Sierra Designs products there is a departure from traditional tent construction and architecture. The result is a ridiculously lightweight, weatherproof and livable tent.
At just a hair over five pounds, the Flash has 41 sq ft of interior space and two side vestibules making it ideal for up to three campers with gear. Though I only picked this tent up this June, it has been on four camping and backpacking trips with me. It has weathered wind and rain with no issues.
