Are you 100% that this is a full suit with hood? as the 'hood' in the pictures appears to simply be a balaclava, which I do not think is attached to this 'suit'.
*edit: after looking around, KSK photos are not easy to find, so I can not be of more help unless you can show more photos of the particular 'suit'.
But check out these 2 videos about the KSK,

You may be interested, the second video has some of KSK in closer quarters.
