3FUL Lanshan 1 Pro

The 3FUL Lanshan 1 Pro is a small 1-person tent that has an interior length of 230 cm (90.6 in) and width of 110 cm (43.3 in). It can still fit a long extra wide sleeping pad that is 76.2 cm (30 in) wide, with a little space beside the pad for gear. The walls slope toward the head and foot ends. The most headroom is in the middle of the tent, under the 125 cm (49.2 in) peak. Sitting up, getting dressed, and getting changed are only possible in the middle. When lying down, the sloped end walls sit close to the head and feet. I am 177.8 cm (70 in) tall and with lofty insulation, a pillow, and a 10.2 cm (4 in) thick sleeping pad, I am just barely not touching either end. That is with the side guylines installed to pull the walls out, which is needed to get the most space inside. Anyone over 182.9 cm (72 in), with a thick sleeping pad, thick insulation, and a pillow, is likely to touch the head end, the foot end, or both. At 671 g (1.5 lb), the Lanshan 1 Pro is light for a 1-person tent, but its small interior gives less space for its weight than tents like the Six Moon Designs Lunar Solo.

There is only one pocket inside the tent, which is small and of little use. The best spot for internal storage is in the triangle of space at the widest point of the tent floor. The vestibule is a good size and plenty of gear fit in it, including a fully assembled camp chair.

The Lanshan 1 Pro has a small footprint. It fits into most campsites, especially when pitched with only the six standard stakeout points and no optional guyouts used.

Overall, the Lanshan 1 Pro suits people up to about 177.8 cm (70 in) tall. The small interior means it is not the most comfortable tent to wait out a long storm in.

The 3FUL Lanshan 1 Pro pitches with six stakes and one trekking pole set to 120 to 125 cm (47.2 to 49.2 in). Because it is a single-wall tent, the fly and inner go up together in an all-in-one pitch. The benefit of an all-in-one pitch is that the inside of the tent stays dry when setting up in the rain. The drawback of not being able to separate the inner from the fly is that the tent must be wiped down after rain or packed away wet. When packing up, the Lanshan 1 Pro can be stuffed straight into its stuff sack without needing to be folded or rolled.

Setup speed is fast if you are familiar with setting up trekking pole tents. I can have the Lanshan 1 Pro set up in about one and a half to two minutes and get the pitch very close to perfect every time. Anyone new to trekking pole tents may need a few tries to learn the pitching technique; but once learned, it is quicker to set up than most traditional poled tents. The pitch can also be adjusted to match conditions: the trekking pole angle can be shifted to suit uneven ground, and the fly can be pitched higher for airflow and headroom or lower to the ground to block wind.

The T-shaped door is one of my favorite features of the tent. The door has one zipper down the middle and one zipper to each bottom corner, so either side can be opened. Getting in and out is easy from either side and, on a slope, a sleeper can put their head at either end and still use whichever side of the door suits the setup. I think that all tents made in this style should use this kind of door system.

The zippers are easy to use with one hand. Each door panel ties back with a toggle and an elastic loop. The tiebacks need two hands to operate but they hold the door open very securely.

The seams on the Lanshan 1 Pro need to be sealed by hand using silicone seam sealer before use. The tent has to be pitched, the sealer painted onto every seam (including places like the guyout points on the fly panels), and then left for about three hours to dry. I would like to see factory-sealed seams on future versions.

Stormworthiness is how well a tent holds its structure in strong wind and how it performs in rain. The 3FUL Lanshan 1 Pro has a pyramid shape with angled walls and no large flat panels. Angled walls shed wind instead of catching it, which makes this shape very stable in wind. The Lanshan 1 Pro has six stakeout points around the bottom edge of the fly. It also has two guyout points on the sides and one guyout point at the back. With the guylines installed, the tent is very stable in wind. The six stakeout points alone are enough for calm nights and keep the footprint small. Using the guylines requires a larger space for the tent, but not much. In wind, the Lanshan 1 Pro is best pitched with the head or foot end facing the wind, which keeps the smallest area of fabric exposed. The door stakeout point is the weak point and should never face into the wind - and a large stake should be used at the door stakeout point. The trekking pole adds strength to the tent structure since a trekking pole is generally sturdier than a standard tent pole and is less likely to break in wind. I have not yet tested the Lanshan 1 Pro in strong wind but have used tents of this style in winds over 100 km/h (62 mph). I expect the Lanshan 1 Pro to maintain its structure at similar wind speeds.

The Lanshan 1 Pro pitches high off the ground and the mesh inner allows wind to blow into the tent. There are solid material flaps at the head and foot ends that can be pulled up to block wind and they work well. For trips with strong wind or with snow, sand, or grit, the solid inner is the better choice than the mesh inner for added protection.

The fly is the main factor in rain. The Lanshan 1 Pro fly is made with polyester, which does not absorb water and does not stretch or sag when wet. A saggy or stretched fly is a larger issue with trekking pole tents because the fly provides some of the structure for the tent; so a trekking pole tent having a polyester fly is a big benefit. The Lanshan 1 Pro also comes in a nylon version but I think the polyester version is the best option.

The fly provides good coverage for the inside of the tent when the door is open and very little rain gets inside when getting in and out of the tent. The bathtub floor is high enough to keep splashback out of the tent in heavy rain.

The 3FUL Lanshan 1 Pro is a single-wall tent. There is no inner wall providing a physical barrier between the sleeper and any condensation that develops on the inside of the fly. Single-wall tents do not develop more condensation than double-wall tents, they just lack the physical barrier. The small interior of the Lanshan 1 Pro makes it easy to touch the walls when moving around the tent and get moisture on yourself or gear. The flaps at the head and foot ends that block wind also act as a barrier between condensation on the fly and the sleeper and gear. This gives some of the protection of a double wall at the two ends of the tent.

The Lanshan 1 Pro has one vent at the peak. The vent is small and I find that it does not add much ventilation. Most of the airflow comes from the large mesh door and the strip of mesh that runs around the bottom of the tent, connecting the fly to the bathtub floor. Limited ventilation means that condensation prevention is difficult.

For condensation that does develop, the Lanshan 1 Pro is designed to manage it well. Condensation that runs down the walls reaches the perimeter mesh and drips to the ground outside instead of into the bathtub floor. Because it is a single-wall tent, the inside of the fly can be easily wiped down with a cloth and the cloth wrung out which results in less water on the tent when packing it away.

I do not mind single-wall tents for condensation because I can wipe them down and, as long as there is enough space inside, I can avoid touching the walls. The small interior of the Lanshan 1 Pro makes the walls harder to avoid, especially for bigger people or anyone using a thicker, bulkier sleep setup such as a thick pad or a lofty quilt. Overall, the Lanshan 1 Pro is slightly below average when it comes to condensation prevention and management.

The 3FUL Lanshan 1 Pro I tested has a 20-denier polyester fly and a 20-denier nylon floor - I have found both to be durable. Nylon is a better material than polyester for floor material because it can deal with abrasion from rough ground and rocks better. The cordage, YKK zippers, attachment points, seams, and stitching are all good quality.

I think the use of only one trekking pole for setup is a durability benefit for the Lanshan 1 Pro. If a trekking pole breaks on a trip (which has happened to me), the second pole can be used to pitch the tent. With a tent that needs two trekking poles, a broken pole can mean looking for sticks to pitch with.

I have used 3FUL products for years and I have not had any durability issues. 3FUL has made versions of the Lanshan tent for years and I have not heard of anyone having issues with them. Around 800 Amazon reviews of the Lanshan series of tents show very few durability issues. The most common complaint is leaking; I think this is most likely from seams that were not sealed properly or from condensation being mistaken for a leak.

3FUL offers lifetime repairs and free replacement parts for tents bought from its own website.

For anyone who fits inside it, the 3FUL Lanshan 1 Pro is one of the best ultralight tents on the market. It is very light, has good performance features, and is an affordable price. Anyone over 182.9 cm (72 in) tall or anyone who spends long hours inside their tent at camp should consider other tents. The Lanshan 1 Pro is for hikers who want the lowest pack weight possible in a tent that is still affordable.
