Kuiu Storm Star 2P, 4-season, 2 person, two doors, two vestibules, 5 1/2# , free-standing dome
Big Agnes Copper Spur UL-2, 3 season, 2-person, two doors, two vestibules, 4#, free-standing dome.
I don't consider the CSUL2 a 4-season tent... I have one. Also, it weighs under 3.5 lbs.
The Kuiu Mountain Star is a nice tent, but I can't fathom hauling a 5.5lb tent for one in this day and age.
Black Diamond Eldorado 2 person single wall tent weighs 4lbs 11 oz with carbon fiber poles. Thank me later.
I've had the Black Diamond Firstlight, the sister version of the Eldorado. Good tent(s), but not real light for a 1P and I dislike not having a vestibule, and the front entry. It's unnecessarily heavy, small, and expensive for what you propose. It's a mountaineering tent made for single use, high altitude climbing.
Planning a later season hunt next year with possible snow. Looking for the lightest, toughest 4 season 2 person tent. Can be a one person
I'd recommend the Big Sky International Revolution, either the 1P or 2P with solid interior... 1P under 3lbs., and a damn good tent.
