The tent has been set up a couple of times but never taken out. Seam sealed. The 3FUL Lanshan 1 Pro is a single-pole, ultralight, non-freestanding tent designed for solo trekking and long-distance backpacking. It utilizes a pyramid-style structure that requires a single trekking pole for setup. The design features a bathtub floor integrated with a single-layer canopy, constructed from silicone-coated nylon for water resistance. It includes one side-entry vestibule for gear storage and internal space management, alongside high-mounted ventilation points to manage condensation within the enclosed sleeping area.
