As thunder rolls in the distance, it's reassuring to know you have a safe backcountry home like the Sierra Designs Lightning 2 FL 2 Person 3 Season Tent ready to go. If the storm's catching up to you quickly, the Lightning's freestanding, double hub pole design lets you set it up anywhere in minutes, and the hybrid singledouble wall design reduces weight, making it easy to scamper off the ridge and find some cover. When the rain starts to fall, the treated nylon floor and and silicone treated polyester fly will keep you bone dry, while the mesh walls and covered foot vent will keep air moving so you don't have to sit in a stagnant pool of boot stink and sticky air. Along with its superlight hybrid wall design, the Lightning's defining features are the dual gear closets, which zip open and separate boots, packs, and smelly gear from the sleeping area, so you can spread out while keeping your gear close at hand. Since this eliminates the need for a vestibule, the door is extra wide, with enough room to accommodate two people sitting side by side, and it saves weight compared to a standard two door design, so the Lightning weighs in at under four pounds, fully packed.
