Why People Love Our Undersleeves

Although Bort Medical’s Sella Dur and Sella Dur with Floc hard thumb splints already comes with a hand sleeve, many people have found it useful to have at least two on hand for alternating while washing, or wearing two at a time for extra support, warmth, or protection.

The thumb splint is constructed out of a rigid plastic, which can become uncomfortable against your skin over the course of the day. This black undersock adds comfort with its soft material and prevents the thumb brace from rubbing or chafing against your skin.

Plus, it’s available in 2 sizes, which will fit comfortably underneath the different sizes of Hand Splints and Thumb Braces.
