While this video is almost purely promotional, it does offer an interesting look at how companies like Fox design mountain bike clothing. Here’s what Fox has to say about Rawtec:
Rawtec is redefining mountain bike apparel. Drawing on our desire to take performance down to a new level of dynamic simplicity, we have pioneered the use of zonal engineering manufacturing techniques in MTB products to enhance the trail specific features of each of these designs. The result is a non-compromising solution to the problems mountain bikers of all levels face while they are out on the trails.
