Propper manufactures its garments in many different fabric variations. Here is a short list of the most used fabrics and their differences.
Fabric Chart

Polyester/Cotton Ripstop

Battle Rip
Tactical uniform fabrics must be comfortable, durable and have excellent color integrity. To achieve this criteria Propper is proud to provide BATTLE RIP. This is an all-season weight, 65% polyester / 35% cotton fabric that is manufactured in a ripstop weave. BATTLE RIP is Proppers fabric of choice for the Public Safety community.

Nylon/Cotton Ripstop

This 50% nylon / 50% cotton ripstop cloth is the fabric of choice for the U.S. Armed Forces w. NYCO (as it is called in short - pronounced NY KO) promotes good color integrity and superior durability

Cotton/Polyester Twill

This 60% cotton / 40% polyester, heavy weight cloth is also a very sturdy and long-life performer in the Public Safety community. Manufactured in a twill weave, this cloth promotes good color integrity and easy care.

Cotton Ripstop

This is a lighter weight cloth in a ripstop weave that breathes well and is initially durable. Consistent with other cotton fabrics, the color will fade quickly, and over time the bottom fibers will lose their strength under industrial wear and laundering. If color integrity is an important end-user expectation, please do not choose this cloth.

NOTE: 100% cotton ripstop fabric is NFPA approved by UL Industries for meeting the NFPA 1975: "Standard on Station/Work Uniforms for Fire and Emergency Services" approval guidelines.

NFPA 1975 Standard for Station/Work Uniforms for Fire and Emergency Services
This standard applies to Fire Service station uniforms made from 100% cotton and flame-resistant fabrics. Recently revised to exclude vertical flammability testing, this standard requires that fabrics do not shrink more than 15% after being tested in a 500 degrees Farenheit oven for 5 minutes. This is the only thermal requirement of this standard. Garments are subject to 3rd party testing and inspections. In the past, NFPA 1975 was often used by industries beyond the Fire Service to specify industrial FR garments. However, with the elimination of vertical flammability testing, this standard is no longer adequate for industrial FR garments.
