3F UL Lanshan 1 Pro Tent Review

The 3F UL Lanshan 1 Pro Tent is an ultralight single-wall trekking-pole tent with a side door and vestibule that can be rolled back in good weather for ventilation and views. The interior has a fully integrated bathtub floor, so you can pitch the tent in the pouring rain and still keep the interior dry. The tent is made of silicone-impregnated nylon (silnylon) and must be seam-sealed by hand before use in rainy weather. This is an easy process that only takes about 30 minutes to complete and a day or two to dry.

While its design shares many features that are common on other tarp-style tents. the Lanshan 1 Pro is remarkably similar to the Six Moon Designs Lunar Solo. The biggest difference between the two is that the Lanshan 1 Pro is made with silnylon which tends to sag a bit when it gets wet, while the Lunar Solo is made with polyester, which doesn’t. Both tents still need to be seam-sealed to waterproof them and both tents are made in China.

Tent Exterior

The Lanshan 1 Pro has a large front vestibule, split down the middle with a zipper, for covered gear storage. The bottom of the vestibule does not reach the ground but is raised to facilitate airflow.

Single-wall tents are prone to condensation, and extra airflow helps minimize moisture buildup inside the tent. There’s also a vent at the peak of the tent to release warm air that collects near the ceiling and causes condensation to form inside.

The tent requires 6 stakes to pitch at a minimum: 5 on the corners and 1 in front of the vestibule. All of the guyout points, including the peak and panels, are reinforced with UHMWPE-gridstop. While you don’t have to seam-seal the fly corners, you will want to seal the needle holes in the reinforced patches on the peak and panels.

When you set up a trekking pole tent like this, it’s best to keep the guylines loose while staking it out, then tighten them once you’ve inserted the peak pole. All of the guyout points have lineloc tensioners, which makes this easy. There are additional panel guyout loops on the side and rear wall, and I would also recommend using them to increase the tent’s interior space and headroom, particularly in wet conditions.

Tent Interior

The Lanshan 1 Pro has a floating bathtub floor that is connected to the tent walls with mesh. This makes it a little easier to pitch the tent on uneven ground and facilitates more airflow through it. The rainfly extends out over the mesh so rain hitting the tent exterior doesn’t drip inside the tent, while internal condensation is designed to roll down the interior walls and out through the mesh. This latter feature isn’t that reliable, however, because surface tension often keeps the water from draining through the mesh. Your best bet is to carry a small towel to mop it up if it ends up dripping on the door. It’s only a small quantity of water.

The bathtub floor has a five-sided shape, so it fits a rectangular sleeping pad and has space for extra gear storage alongside your pad inside the tent. It’s big enough for a medium-sized dog. There is however, only one small mesh pocket on the interior of the tent, located at one of the ends.

The corners of the bathtub floor have guylines attached that can share a stake with the corners of the fly. These interior guylines give the bathtub floor its height, to prevent standing water from entering the tent. It’s a nice detail.

Packaging

The Lanshan 1 Pro comes with a compression sack, attached guylines, extra guylines, a seam-sealing syringe, and 10 tent stakes. You do need to purchase silicone-based seam-sealer separately though. We dilute ours 50/50 with white gas so that it soaks into the seams more easily and then paint it on with a small brush.

The Lanshan 1 Pro packs up quite small when it’s stuffed into its stuff sack, making it very easy to carry in a smaller volume backpack.

Recommendation

The 3F UL Lanshan 1 Pro is a solid value for the money. While silnylon tents have been somewhat eclipsed by ones made with polyester because they don’t stretch when they get wet, silnylon is still a highly packable fabric that will last a long time with proper care. While there is some benefit to buying a polyester Six Moon Designs Lunar Solo ($260) instead, the Lanshan 1 Pro is still a perfectly good tent in its own right. If you’re on a tight budget or you want to try using a single wall tent without going bankrupt, the Lanshan 1 Pro is a good option.
