The norbornane ring system in the title molecule, 8,8-dimethyl-3,3a,4,5,6,7-hexahydro-3a,6-methanobenz[c]isothiazole S,S-dioxide, C10H15NO2S, is regular with normal bond lengths and angles. The bridgehead bond angle is 92.5 (2)°. The five-membered ring of the sulfonylimine moiety adopts a flattened envelope conformation. The crystal structure is stabilized by weak C—HO hydrogen bonds.
