This Nike Sport Loop band was woven from nylon thread to create a hook-and-loop closure. These bands were available for the 41 mm and 45 mm Apple Watch models, and were offered in sizes to fit 130–200 mm wrists and 145–220 mm wrists. The bands also fit older Apple Watch sizes.
This band uses 2 colors. The primary color is Sequoia, a shade of olive green, and an accent color “Pure Platinum,” Nike’s description of light metallic gray. The “Pure Platinum” accent is woven with the Sequoia color to create a light version of Sequoia that is used for the part of the band that features Nike’s tagline, “JUST DO IT” that is woven on the adjustable hook-and-loop closure of the Sport Loop.
Apple described this Nike Sport Loop band:
“Breathable and lightweight, the Nike Sport Loop is designed for fitness. The iconic Nike ‘Just Do It’ logo is woven right into the soft nylon using an innovative technique. A hook-and-loop fastener makes for quick and easy adjustment, and dense loops on the skin side provide soft cushioning while allowing moisture to escape. On the reverse side, the attachment loops are securely anchored for superior durability.”
