These will not burn, period.

They're made with 100% aramid, no nylon filler. It's the most flame-retardant polymer you can get. The only material certified for use in fire-fighting equipment.

We treat these with a light wax coating so they stay tied and they're easy on your eyelets.

Waxed to stay stay tight
