The 26mm-wide high-memory woven Nomex straps feature ESS's patented Speed Clips, which make strap adjustment quick and easy, even with gloves on. This system functions well with all major structural firefighting helmet designs, and is compatible with the ESS Innerzone 1 and ESS Innerzone 2 mounting brackets.
