40d ripstop nylon
40D ripstop nylon hits a sweet spot for makers who want gear that is light enough to carry all day yet tough enough to handle real use. Its signature grid of reinforced threads stops small tears from spreading, so a snag stays a snag instead of becoming a split seam.
What Makes 40D Ripstop Nylon Special
The "40D" stands for 40 denier, a measure of yarn thickness. That fine yarn keeps the fabric thin and packable, while the ripstop weave adds strength you would not expect from such a light material.

What to Look For
Check each listing for its finish. Uncoated ripstop breathes well for apparel and liners, while coated ripstop nylon or DWR-treated options shed water for shelters and rain gear. Also consider color, hand feel and whether the fabric suits your machine and needle setup.
