Apple's own Sport Band is a hard one to beat but we think Nomad is onto something with their new Sport Strap. Compatible with every Apple Watch model, the fitness-focused strap is constructed out of durable, waterproof, and oil-resistant FKM fluoroelastomer rubber that is perfect for intense activity with soft flexibility for all-day comfort. They've also designed it to be lightweight and enhanced the band's ventilation with channels in the bottom of the strap for increased breathability and you've got a custom-designed pin and tuck closure system for a clean and secure fit.
