WHY GO SILNYLON?

Silnylon cannot be factory taped like PU Nylon due to its physical properties, it requires you to seal it outdoors with silicone. Why would we use this fabric with seemingly obvious flaws in the more advanced Lanshan PRO?

It was a decision we made in terms of fabric aging time, tear strength. We think the places that professional hikers reached will be harsher and have stronger UV rays, which puts higher demands on the aging and strength of the fabric.

The aging performance of Silicon-PU Nylon in this data is based on our years of repairing tents in the Chinese market, including PU Nylon of brands such as MSR, BigAgnes, 3FULGEAR, etc.

Since we haven’t repaired the aging SilNylon tent, the aging performance of SilNylon is based on feedback from our customers and users of backpackinglight.com

The tear resistance data comes from our experiments on one-way tearing of single-ply fabrics with incisions.

SilNylon won’t tear apart like paper when subjected to forces exceeding its tear strength. Instead, its slippery fibers will align and create a strong anti-tear force. Even if the tent is damaged at this point, it won’t collapse and can continue to provide protection for the user.

The waterproofing data is derived from our tests using the WX Air PowerPressure device, conducted at 25 degrees Celsius. The video of this experiment is available on our YouTube channel.

The waterproof level required to effectively prevent raindrops from penetrating is 1000-2000mm, which is why we strive to achieve this value with SilNylon. The water resistance pressure of PU Nylon far exceeds actual usage requirements because our research found that only by increasing the thickness of the PU layer to this level can a PU tent achieve a lifespan of 5 years.

Packing List

Set-up Instruction

Step 1: Secure the four corner pegs (A, B, C, D) to form a perfect rectangle. (Do not install pegs E and F at this stage.) Align the corner’s guyline with the tent’s ridgeline (seam) in a straight line to enhance stability

Step 2: Install peg F 1.2m (47 inches) from the inner tent. Use a 1.2m-1.25m trekking pole to raise the tent structure. Attach the vestibule guyline G to peg F.

Step 3: Setting Up Peg E & Guylines

Pull point E outward and secure it with a peg.
Attach guylines to anchor points G1, G2, G3, then secure them with pegs.
