The 3F UL Gear Lanshan 1 (2026) is a single-person ultralight pyramid-style (tipi) tent pitched with one trekking pole, 120–125 cm long. Its non-freestanding design relies on stakes and tension rather than dedicated poles, which is the main reason it gets down to 770 g in minimum trail weight (inner plus fly only) and 930 g fully packed with stakes and stuff sack.
The double-wall build pairs a silicone-impregnated 15D nylon fly with a PU-coated 20D nylon bathtub floor; the inner is full mesh, which helps airflow but offers less warmth on cold nights — this is a 3-season tent, not a winter one. A 2.07 m² floor and 125 cm peak height give one person and a pack enough room, with a single 0.8 m² vestibule for boots and a stove.
Seams come factory-sealed, the zipper is YKK, and the tent pitches with nine stakes across three guy points. It suits thru-hiking and fast, light trips where minimizing weight matters more than having a second door or a larger vestibule.
