For athletes we recommend Sport Loop or Solo Loop — sweat-resistant and lightweight. Business users reach for Milanese or leather. Outdoor athletes go for Alpine, Trail or Ocean (Ultra). Lifestyle users combine nylon and stainless steel. Families choose flexible silicone sport bands. Travellers prefer quick-release bands. Sustainable options: recycled nylon, vegetable-tanned leather and compostable packaging are available. Crossbody lanyards for Apple Watch are available — ideal for care workers or sports coaches who need the Watch visible.
