The “XL Band” product itself already comes with this silicone band as of 12/2023. You might purchase this if you have the older/previous nylon band or if you wanted a brand new “band” part for your newer XL Band.
The NEW XL BAND as of 12/2023 comes with this new super soft, smooth, and comfortable silicone black band made specifically to fit the XL Band. This band is not adjustable like the Alternative Band but still fits almost everyone from a small child to a larger adult (the band goes from 4.0″ to 8.5″ circumference for wrists or kids’ ankles).
(NOTE: Does NOT come with the Chip or the Face of the XL Band. This is only the band which holds those.)
