Since we make great garments that last, we may as well make them function all the way. The fact is that last year we gave them the choice. Some of the new jackets feature the brand new coated highly water resistant ventilation zippers in the arm-pit. We use only high quality YKK zippers. In stress areas we tend to use mainly coil zippers due to that they are more durable.
Molded zippers look better.
But their teeth can be crushed, and then the zipper is useless. For our intended use it is impossible to avoid an occasionally broken zipper. However, we experience very few such problems. These are of high quality, and nickel free to avoid allergic skin reaction. Should there be a problem with the snaps falling off, then this is generally due to how it has been attached to the garment.
