Hand Jam -- Sizing
To provide the best fit, the HAND JAM is available in 5 sizes — each in a unique colour.
Measure: Palm circumference — just below the knuckles, hand should be relaxed.
Fit: Secure when hand is closed jamming, relaxed when hand is open.
Stretch: The leather will soften and mold to your hand like a new pair of climbing shoes — becoming uniquely yours.
