If you need further sizing just let me know. **Q: How do you determine your hand and thumb size? this item is non-returnable and would like to size it correctly.** A: As the pre-ordering/packaging instructs, you need to measure around /maybe slightly below the knuckles. It also mentions that for 'plus' sizes, they are designed about a 'half size larger in the hand and one size larger in the thumb for those with enlarged thumbs'. ( took this quote directly off the package they arrived in) I am sure it should also be on the order form. There was also an 800 # if you need more questions answered than I could provide - 800-821-9319. Hope this helps. **Q: Has anyone cut this to have it be less bulky? thanks** A: If yours is like mine, i would not try it due to the stitching causing it to ravel a loose. I have an actual comfort cool from the ortho clinic and thought I was ordering the same one for backup, while washing original one, but have found out theses are NOT comfort cools by any stretch of the imagination & is just a poor replication of one. My thumbs on mine are too long & extend out far above my nails. What is shown is a "real" comfort cool" & mine doesn't look feel nor wear anything like my original one. A waste of money, but I do use them for back-up for only short periods of time since, it causes an abnormal thumb extension/position when wearing it, where the real splint does not. Good luck!!! **Q: do you have the comfort cool thumb cmc restriction splint for the left hand in size small ?** A: I have a right hand medium. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good solution for an arthritic thumb. *by B***V on March 28, 2026* Seems to be working well for me when I wear it at night.
