You think the military glasses are too much to fit Dota2? Check out the version of the cap without them:

Fun fact: When you lay out a rather round object such as the cap in a quadratic UV space for the texture, theres usually space left in the corners. Thats why I added the glasses. Apart from the texture space, I was also way below the polycount limit.
Although some might say that this does not fit Dota2, I think it's right on the edge. Sniper is pretty modern anyway, with a handgun and zoom optics. Also, the glasses are hardly visible ingame, only in the profile picture.

Flavour Text / Ingame Description:
Although the cap is being worn by sharpshooter recrutes as well, the golden 'Kardel Elite' Badge is given only to those worthy.
