Terra Nova, the British outdoor brand, plans to display what it is calling the lightest double-wall tents in the world at the Outdoor Retailer show in Salt Lake City in August. The tents, for one person and two people, use a proprietary fabric called Ultra. The "Laser Ultra 1" tent weighs 495 grams, and the "Laser Photon 2" weighs 880 grams, which Terra Nova says makes it the first two-person double-wall tent weighing less than 900 grams.
