The Nemo Obi 1P Tent is the Jedi tent of the Nemo line. At 2 lbs. 8 oz. you could almost clip this super lightweight backpacking tent onto your trick gear belt next to your light saber. Unlike other ultralight tents in the under 3 lb weight class, the Nemo Obi offers a full array of features: a large vestibule, extra foot vent, gear pocket, overhead light diffusing pocket, and Jake's feet for super easy one-person, one pole set up. The Obi certainly lives up to Nemo's innovative, quality standards that say you don't have to sacrifice every feature just to shave ounces off your tent. Obi Wan would be psyched to take this on his next mission.
If you're still wanting to shed every last ounce you might be the ultralight type to go for Nemo's Meta tent series that utilizes trekking poles so you don't need to carry tent poles. Available in a one-person, one pole version and the two person, two pole version; there's a reason this tent won Backpacker Magazine's Editor's Choice Award last year. The Meta 1P / 2P is a pretty slick design and is so light it works great as an emergency bivy as well.
