If you're shopping for a solo ultralight tent, you've probably landed on two names from 3F UL Gear: the Lanshan 1 and the Lanshan 1 Pro. On the surface they look nearly identical — both are one-person, trekking-pole shelters that pack down to the size of a water bottle. But under the flysheet, they're two very different tents built for two very different hikers.
The short version: the Lanshan 1 is a double-wall tent that's ready to pitch straight out of the bag — ideal if you're new to ultralight backpacking. The Lanshan 1 Pro is a lighter, tougher single-wall shelter for experienced hikers who want maximum performance and don't mind a little DIY. Let's break it down.

1. Weight and Packed Size: The Pro Shaves Every Gram
Both tents are genuinely ultralight, but the Pro takes it further. The Lanshan 1 starts at 740 g (1.63 lbs), while the Lanshan 1 Pro trims that to 666 g (1.46 lbs) — a saving of 74 g. That doesn't sound like much until you remember this is a tent that already weighs under a kilo; the Pro is roughly 10% lighter.
The Pro also packs down smaller: 26×14×14 cm versus the Lanshan 1's 32×14×14 cm. In a frameless pack or a 40L ultralight setup, those few centimetres matter.
And there's a hidden option for gram-counters: the Pro ships with removable condensation guards at the head and foot ends. Cut them off and you drop roughly another 20 g.
2. Double-Wall vs Single-Wall: The Biggest Difference
This is the decision that shapes everything else.
The Lanshan 1 is a double-wall tent: a separate inner tent (mesh or solid nylon) hangs inside a waterproof rainfly. The gap between the two layers manages condensation beautifully — moisture passes through the mesh and collects on the fly, not on your sleeping bag. You also get the flexibility to choose a 3-season breathable-mesh inner for warm-weather ventilation, or a 4-season solid inner that blocks wind on exposed campsites.
The Lanshan 1 Pro is a single-wall tent. One layer of fabric does everything, which is exactly how it saves weight and packed size. To fight condensation, 3F UL Gear added solid nylon condensation guards at the head and foot — the two spots where a sleeping bag is most likely to touch wet fabric. It's a clever, practical solution, but physics is physics: in humid, still-air conditions, any single-wall tent will collect more interior moisture than a double-wall design.
3. Fabric and Durability: Two Different Philosophies
Lanshan 1: Proven, Practical, Waterproof
The Lanshan 1 uses a classic and reliable formula: a 15D nylon rainfly with silicone/PU coating rated at 5000 mm and a 20D nylon bathtub floor rated at 6000 mm. All seams are factory-taped with waterproof polyurethane tape, and the floor is PU-coated for complete waterproofing. Translation: it's rain-ready the moment you take it out of the box. The 2026 version (released July 2025) upgraded the waterproof zipper, swapped plastic hooks for metal ones, and reinforced the high-stress vent area with 20D UHMWPE grid nylon.
Lanshan 1 Pro: Double-Sided Silicone, Built for Storms
The Pro takes a more radical approach. Its 20D fabric is coated with silicone on both sides — no PU layer at all. This maximizes tear resistance and fabric longevity, because unlike PU-coated nylon, double-silicone fabric doesn't delaminate or degrade the same way over years of UV exposure. In tear tests, the silnylon version resists 45 N of tearing force, and even beyond its limit, the slippery fibers align to resist propagation rather than ripping like paper.
The Pro also comes in two fabric flavors:
- 20D Silnylon (2025 version) — maximum tear strength (45 N) for extreme weather and high-altitude use.
- 20D SilPoly (2026 version) — water absorption of just 0.5% (one-tenth that of silnylon), which means it doesn't sag when wet. Easier to live with in sustained rain.
There's one trade-off you must understand: double-sided silicone fabric cannot be factory-taped. You'll need to seam-seal the Pro yourself before its first wet outing (about an hour's careful work with a tube of silicone), or add our professional seam-sealing service for €23, done by our most experienced outdoor instructors.
4. Setup: Nearly Identical, Pro Has One More Step
Both tents pitch with a single trekking pole set to 120–125 cm and follow the same core sequence: peg the four corners into a rectangle, raise the structure with the pole, then tension out. The Pro adds a third step — pulling out point E and anchoring guylines G1, G2, and G3 — which gives it a taut, storm-ready geometry with more anchor points than the standard Lanshan 1.
Both tents now feature the full-length T-zip door. On the Pro, three high-quality YKK zippers let you open the door completely, so you can enter from either side regardless of terrain or wind direction.
5. Price and Value
The Lanshan 1 sells for €103 — remarkable value for a genuine 740 g double-wall shelter with taped seams. The Lanshan 1 Pro sits at €134 (currently discounted from €178), which buys you the lighter weight, double-silicone fabric, removable condensation guards, and an award-winning design that's been lab-verified and celebrated by outdoor experts.
The honest framing: both are budget-friendly compared to Western ultralight tents that cost €450+. The question isn't "which is the better deal" — it's "which tent matches how you hike."

Buy the Lanshan 1 if:
- This is your first ultralight tent and you want it to work perfectly with zero fiddling
- You camp in humid climates or near water where condensation is a nightly battle
- You like the idea of swapping between a mesh summer inner and a solid winter inner
- You'd rather spend the €31 difference on a footprint or a better sleeping pad
Buy the Lanshan 1 Pro if:
- You've already logged nights in the backcountry and understand single-wall trade-offs
- You're chasing a sub-700 g base weight and every gram counts
- You face serious weather — high winds, high altitude, long trips where fabric longevity matters
- You're comfortable seam-sealing (or happy to pay €23 to have it done right)
Frequently Asked Questions
Is the Lanshan 1 Pro worth the extra money?
If you're an experienced hiker who cares about weight and fabric performance, yes — the 74 g savings, double-silicone fabric, and storm-ready guyline geometry are real upgrades. If you're newer to ultralight hiking, the standard Lanshan 1's taped seams and double-wall comfort deliver more practical value per pound spent.
Does the Lanshan 1 Pro leak without seam sealing?
Yes — any double-sided silicone tent will leak through the stitch holes until the seams are sealed. Seam-seal it before your first trip, or add our €23 seam-sealing service at checkout (orders with the service may ship 3–5 days later).
Which one handles rain better?
The Lanshan 1 is fully waterproof out of the box with 5000 mm fly and 6000 mm floor ratings. A properly sealed Lanshan 1 Pro is also highly weatherproof — and if you choose the 2026 silpoly version, the fabric absorbs almost no water and won't sag or lose tension in sustained rain.
Can either tent handle winter conditions?
Both offer 4-season inner/variant options. The Lanshan 1's solid 4-season inner blocks wind for winter camping, while the Pro's silnylon option (45 N tear strength) is the better choice for genuinely demanding terrain, high altitude, and severe storms.
Do I need trekking poles for these tents?
Yes — both the Lanshan 1 and Lanshan 1 Pro require one trekking pole of 120–125 cm for setup. If you don't hike with poles, you can substitute a fixed-length pole of the same height.
