| Signature | Visible grid pattern |
Ripstop is a weaving technique that reinforces fabric with a grid of thicker threads at regular intervals, so a small tear or puncture is stopped from spreading. It gives lightweight nylon or polyester high tear strength for its weight, which is why it’s everywhere in tents, sleeping bags, shells, and packs. The grid pattern is its visible signature.
Strength for the weight
Its tear resistance is measured alongside fabric weight in denier; tougher abrasion-focused cousins include Cordura and ultralight Dyneema.
Frequently asked questions
What is ripstop fabric?
Ripstop is fabric woven with thicker reinforcement threads spaced in a grid throughout a lighter base weave. If the fabric is punctured or nicked, those reinforcing threads halt the tear at the edge of the grid square instead of letting it run, giving high tear resistance for very little extra weight.
Where is ripstop used?
Almost everywhere weight and tear strength both matter: tent bodies and flies, sleeping bag shells, down and synthetic jackets, rain shells, kites, parachutes, and lightweight packs. It's usually nylon or polyester, sometimes with high-strength fibers woven into the grid.
Is ripstop waterproof?
Not by itself — ripstop describes the weave, not waterproofing. Many ripstop fabrics are treated with a DWR finish or laminated/coated to add water resistance or waterproofing, but plain ripstop is simply a tear-resistant fabric. Check the specific fabric's coatings for its water performance.
