They look rather thin and has brown shade, my guess is they are some "neuro" type like Maxitex Neuro (more brands offers similar style, they are usually thinner than ordinary surgical gloves and has this brown shade) and some silicone oil or lubricant is applied so they look transparent and glossy.
