Find your size

S/M: Fits wrists 5–6.4" (12.7–16.3 cm)
Best for smaller wrists or if you prefer a snug fit.

M/L: Fits wrists 6.5–8" (16.5–20.3 cm)
Best for average-to-larger wrists or if you prefer a little more room.

 

Not sure? Choose M/L. Wily should feel secure, but not tight.

 

Tried one of our prototypes? Our prototypes fall between the two sizes. If yours felt snug, choose M/L. If it felt a little loose, choose S/M.
