For durability and ease of use, we use metal teeth on the zipper for our pants. There's something about a metal zipper that just feels right!
Currently, we only use brass for our zippers. Brass has a high CO2 footprint but is 100% recyclable, if removed from the polyester tape. The removal of the tape is possible but must be done by hand, which is done in our take back program. Brass is extremely strong, durable, long lasting, and passes the first rule of sustainable production: make something that lasts!
All of our zippers are made by YKK, and all are Oeko-Tex certified. This provides us the comfort of knowing that all of our zippers have been tested for harmful susstances.
