The Catalyst Sport Band for Apple Watch combines distinctive styling with performance features for the Apple Watch. The band is built with a triangular truss pattern that creates maximum breath-ability and this is also the system for clasping the band together. The arrangement of the pattern creates more adjust-ability than any other sport strap giving the user more range for fit. Comfort is key with the super soft, hypoallergenic silicone band. The attachment system of the strap is designed to be easy to put on and extra secure with our double locking clasp. The selection of stylish Catalyst Sport Bands come with a quick release spring bar making it quick to change out between your Apple Watch and Catalyst Apple Watch waterproof and impact protection cases.
