ripstops

Ripstop is a fabric design characterized by a regular grid of thicker reinforcement threads interwoven at intervals. The grid creates small squares that help prevent tears from spreading beyond the square, improving tear resistance without a large weight penalty. This combination of light weight and durability makes ripstop fabrics a common choice for outdoor and performance textiles.

Ripstop fabrics are usually made from nylon (polyamide) or polyester, though blends exist. The reinforcing yarns are woven into the base fabric in a repeating pattern, forming square or rectangular blocks typically a few millimeters across. The grid can be more or less visible depending on the material and finish. Some ripstops are coated or laminated to enhance water resistance, windproofing, or durability, producing treated versions suitable for weatherproof gear.

Common uses include tent fabric, backpacks, sleeping bags, rainwear, hammocks, and other ultralight outdoor equipment. In addition, ripstop textiles have military origins and have been used for parachutes and gear where tear resistance is important. The pattern is also found in sails, kites, and various consumer products that benefit from a balance of strength and lightness.

Advantages of ripstop fabrics include improved tear resistance relative to their weight, versatility in coatings and finishes, and broad availability. Limitations include the fact that the grid does not make the fabric impervious to tearing and that the pattern may be visible or affect aesthetics. Care typically involves gentle washing and avoiding high heat, especially for finished or coated ripstops, which may require line drying to preserve coatings.
