The trousers "Pixelka" entered service with the Russian army in the early 2014s.It's very durable, but breathable qualities not the best. So, it's good suit for CBQ, but not the best for forest and Mountains.   

In addition to the Russian army, it is used by other paramilitary units of the Russian Federation.   

Doesn't have velcro panels, so, all patches you need to sewn to it. 

This is a sale version with non-original fabric.
