3FUL LANSHAN 1 PRO

The 3FUL LANSHAN 1 Pro is a 1-person single-wall A-frame/pyramid tent supported by a single trekking pole. Compared to the double-wall LANSHAN 1, it trades the separate mesh inner for a lighter build: a 20D silnylon fly rated to 2,000 mm, a 20D nylon bathtub floor rated much higher at 5,000 mm, and an asymmetric footprint giving 2.75 m² of floor space. Trail weight of 690 g and packaged weight of 840 g make it one of the lighter shelters in the 3F UL Gear lineup, actually lighter than the standard double-wall LANSHAN 1. A 0.8 m² vestibule adds room for a pack and boots, bringing total living space to 3.55 m². The fly's lower waterproof rating relative to the floor suggests this shelter is built more for dry-to-moderate conditions than for prolonged heavy rain. It fits ultralight backpackers and thru-hikers who prioritize minimum weight and a more compact tent, accepting a single-wall design that's more prone to interior condensation than a double-wall setup. Seam sealing is required before first use.
