Active Strap Pro is built with waterproof leather bonded to an FKM interior for ultimate versatility. Ventilation channels in the FKM liner allow for breathability where sweat and water would otherwise build up. No matter what you put your Apple Watch through, simply rinse with water and Active Strap Pro is ready for a night out.
A high-tech tanning process developed in Germany infuses this leather with natural lipids, making a thoroughly hydrophobic strap without using any artificial surface coatings. Salt water, sweat, dirt and sand are all easily wiped off without damaging the strap’s waterproof nature.
Active FKM Design
We chose FKM on the interior of Active Strap Pro for its flexibility and durability. FKM is a high-performance fluoroelastomer used in demanding applications where more common materials aren’t up to the task. The comfortable microtexture on Active Strap Pro's FKM interior creates a strap ready for all-day wear, no matter what your day looks like.
Custom Lugs. Modern Style.
Available in both Black and Classic Brown waterproof leather, Active Strap Pro is fit with our custom designed, metal injection molded (MIM) lugs and buckle. High tolerance fit and sharp details are created with this industry leading 316 stainless steel.
