Thumb hole is a little tight, very straight – the metal bar could need a little more bend at the end (See other users picture). Still, would buy this wrist support again: my much much much more expensive medical wrist support chafed at the edge of my hand and the velcro is already failing after just one month. So since i probably have to wear a wrist support for some more month, i bought some of these here. (esp. since i can reuse my better metal bar ��
