Let’s get this straight—300T Pongee fabric isn’t just some textile jargon. It’s a lightweight, finely woven polyester fabric known for smooth texture, slight sheen, and versatility. The “300T” stands for 300 threads per square inch, which gives it a tight weave and enhanced durability.

How is 300T Pongee Fabric Made?
Thread Count Explained (Why 300T Matters)
The “T” in 300T is short for thread count. In 300T Pongee, 300 threads are woven per square inch of fabric—more than enough to ensure strength without bulking up. That high thread count makes it denser and smoother than lower-T Pongees like 190T or 210T Pongee Fabric.
A tighter weave = better performance. It’s science.
Manufacturing Process of Pongee
Pongee is usually made from 100% polyester using fine filament yarns. The weave is plain—warp and weft intersect at right angles. It’s then dyed, often piece-dyed for uniform coloration, and finished with coatings like PU or PA for extra functions (water resistance, anyone?).
Technical Specs of 300T Pongee Fabric
Let’s talk numbers—because details matter.
GSM Range
300T Pongee typically ranges between 60 to 90 GSM. That’s light but not flimsy. Just right for linings, outer shells, and even camping gear.
Composition Breakdown
Most variants are 100% polyester, but some blends with nylon exist too. Polyester brings strength, wrinkle resistance, and affordability to the table.
Width and Yarn Count
- Full Width: Usually 57/58” or 59/60”
- Possible Yarn Counts: 50D × 50D, sometimes 75D × 75D depending on application
What Makes 300T Pongee Special?
Appearance and Feel
Silky. Subtle sheen. Smooth like a cat’s purr. That’s how 300T Pongee feels. It doesn’t scream luxury, but it whispers comfort.
Coating & Functional Finishes
300T Pongee is often enhanced with coatings such as:
- PU (Polyurethane) – Adds water resistance
- PA (Polyacrylate) – Improves softness and colorfastness
- W/R (Water Repellent) – Great for outdoor use
- AC (Anti-static Coating) – Keeps the cling at bay
Some even get PVC or TPU coatings for heavy-duty applications.
Water Resistance, Breathability & Durability
With PU or WR coatings, it handles light to moderate rain like a pro.
Breathability is decent but not exceptional—it’s no cotton.
Durability? You bet. It resists tears, creases, and even some UV damage.
Common Applications of 300T Pongee Fabric
Outerwear and Jackets
Used as shell fabric in windbreakers and raincoats. Not bulky, but strong enough to handle a hike through brambles.
Linings and Umbrellas
Ever opened an umbrella and felt that silky inside? That’s often 300T Pongee. Same goes for jacket linings—soft, strong, and slick.
Tents and Sleeping Bags
With coating, it becomes water-resistant and windproof—perfect for lightweight tents and sleeping bag linings.
Backpackers love it. And so do their backs.

Final Thoughts
300T Pongee fabric is like the Swiss Army knife of textiles—versatile, practical, and surprisingly elegant. It does the job whether you’re sewing jackets or pitching tents. The 300 thread count gives it just the right mix of smoothness and structure. Throw in some coatings, and you’ve got a material that fights the elements without fighting your wallet.
For fabric engineers, designers, or curious DIYers, it’s a solid pick.
FAQs About 300T Pongee Fabric
1. Is 300T Pongee waterproof?
Not by default. But with PU or W/R coatings, it becomes water-resistant enough for jackets and tents.
2. What does 300T mean in fabric?
It refers to 300 threads per square inch. Higher thread count means finer weave and smoother feel.
3. Can 300T Pongee be used for upholstery?
Not ideal. It’s too lightweight and may not withstand the abrasion that upholstery demands.
4. Is it safe to iron 300T Pongee?
Use low heat. Polyester melts at high temperatures. Steam carefully—or skip the iron.
5. How does 300T compare to 190T or 210T?
300T is smoother, tighter, and more durable. It looks and feels more refined than lower thread count versions.
