Tested by IvyEverything in this shop went out on a real trip with me before it earned a listing. Wet, cold, dropped, packed out. This one passed.
About a pound of carbon steel and 600D Oxford cloth, folded down to the size of a pencil case. A folding camping stool only helps if you will actually carry it, and this one disappears into a tote bag until the moment you need somewhere to sit.
About 1 pound, light enough to clip to a daypack and forget it is there.
Folds to roughly 10.6 by 4 by 2 inches in about three seconds, so it fits a tote bag or a tackle kit.
Reinforced carbon steel frame rated to roughly 265 pounds, which is real seating and not a novelty.
600D Oxford seat shrugs off wet grass, sand and campfire grit.
Seven styles including black, khaki, khaki and red, larger sizes, and one with a detachable crossbody strap.
Trailheads, fishing banks and long lines at the ranger station, you will end up carrying it everywhere.
