River Country makes several tents with 5×7 footprint around 3lbs. I have no experience with them; just noticed that they exist.
I’ve had a River Country Products Trekker Tent 2.2 for perhaps 5 years and it really ain’t bad given the low-low price. Mine weighs 2.82 pounds rolled and rubber-banded with guys but no pegs/poles/storage bag. It’s a classic 5′ x 7′ A-Frame “pup tent” partial 2 wall with the fly and sides made out of PU Coated Polyester (ahead of its time there). Ton ‘O room for one; tight for two.
Like many of us here I have too many tents, from big Coleman pop-up dome for six to X-Mid 2 Pro, but if one were on a serious budget or just starting out I’d give the Trekker Tent 2.2 a look, or maybe better yet the Trekker Tent 2V (V for nice vestibule); looks kinda nifty.
