NOTE - If you are allergic to neoprene, we suggest you not wear this wrist brace. Hand washes in cold water with mild detergent and air dry. Do not use bleach or fabric softener. BREATHABLE & ADJUSTABLE - It is made of an antimicrobial-treated neoprene blend to minimize sweating. Three adjustable elastic straps with a hook and loop fastener provide compression and stability. It has strong adhesion and is not easy to fall off. FITS RIGHT AND LEFT HAND - There are two openings on the wrist brace, which fit for right and left hands. The thickened edging design will not scratch your hands. Suitable for a wrist circumference ( minimum part ) up to 24cm / 9.5 inches and 26 cm / 10 inches, which can be used by both men and women. STABLE SUPPORT - Our wrist brace adds a lightweight aluminum bar, which is ergonomic and fits the curve of the wrist. Not only does it not restrict the movement of your fingers ( not as flexible as usual ), but it also makes your wrist more stable and rests and recover. RELIEVES PAIN DAY & NIGHT - Our wrist support lining has added a soft pad, which can maintain comfortable wearing throughout the day. Effective for carpal tunnel syndrome, tendonitis, or simply just a wrist sprain or strain. It will give your injured wrist the support during sleep or rest.
