I measure 11.5" forearm and 10" hand circumference. The max sizing on chary is 9.5" what other brace would you recomend? Or is the xl C1 ok to use?
The measurements give would indicate that even the XL might not be quite big enough for you. The chart usually would say something like 9.5" or larger if it would be able to work for a larger size but this has a definite cut off. There are some other brands of wrist supports that use a different measurement to get the sizing so you may could try another brand to see if it has a closer match.
is the wrist cup adjustable?
This wrist support does not have a cup position that it will let you adjust to. There are other Storm wrist supports designed to let you cup your wrist more if you needed this feature. You may check out the C2 and C4 supports for that.
is the size L/X an XL size or what?
