The Lanshan 1 Pro is 3F UL Gear's tarp-tent hybrid for experienced ultralight hikers. It's a single-wall, one-person shelter that keeps the weight right down while still giving you a fully enclosed space for the night. This is the 2026 version in grey Silpoly.
The Pro series uses fabric that's silicone-treated on both sides rather than PU coated on one. That gives it excellent tear strength, but it means the seams can't be factory taped. Silpoly also absorbs less water than silnylon, so the shelter sags less when it's wet. T-zip doors with three YKK zips open fully, so you can get in and out easily whichever way you pitch it.

If you'd prefer a double-wall tent, look at the Lanshan 1. Seal the seams before your first trip with Gear Aid Seam Grip + SIL, and pick up some trekking poles if you don't have them. Also available in khaki. See the full 3F UL Gear range.
