When shopping for a tent, comparing specs like weight and packed size is easy—but what about those cryptic fabric details? At KingCamp, we engineer every tent with purpose, down to the fibers in its fabric. Here’s how to decode those numbers and choose the perfect shelter for your adventures.


The Formula Explained

Tent fabrics are described with a string like this:
"20D x 330T ripstop nylon | 1200mm Durashield® PU/Si coating"

Let’s break it down:

1. Denier (D): Fiber Thickness

  • What it means: Denier measures fiber density (grams per 9,000 meters of yarn). A higher Denier = thicker, heavier fibers.

    • Example: 40D nylon has 1.5x thicker fibers than 20D.

  • Strength isn’t just about Denier: Material matters too! Strength hierarchy:
    Nylon < Nylon 6 < Nylon 6.6

    • KingCamp’s approach: We use ultra-strong Nylon 6.6 for high-stress areas (like the floor in our Hubba NX tents) but opt for rugged polyester (“packcloth”) in the Elixir series for UV/abrasion resistance.

2. Thread Count (T): Weave Density

  • What it means: Threads per square inch. Higher T ≠ always better—it depends on the fabric type.

    • Example: Our 20D Nylon 6.6 (300T) is lighter yet stronger than 68D packcloth (210T).

  • KingCamp’s secret: We balance thread count with fiber type and tent placement (e.g., rainfly vs. floor).

3. Coatings: Waterproofing & Durability

  • 1200mm rating: Measures hydrostatic head (how much water pressure the fabric can withstand before leaking).

  • PU/Si coating:

    • PU (inner layer): Seals seams; maintains tear strength.

    • Silicone (outer layer): Beads water, resists UV, and keeps fabrics supple.


What Really Matters for Your Tent?

  • Backpackers: Prioritize low Denier (10D–30D) for weight savings—but check for reinforced stress points (like our Carbon Reflex’s triple-stitched corners).

  • Car campers: Opt for high-Denier fabrics (40D+) like packcloth for durability.

  • All users: Look for at least 1,200mm coating (3,000mm+ for heavy rain).

Pro Tip: Lighter tents trade some durability—handle with care or choose models with strategic reinforcements.
