These are very conveniently sized, built tough, and are pretty comfortable to wear. What more can you ask for in a small/medium sized ruck? These are about the size of a U.S. assault pack if you put all the compartments in to one compartment. Perfect as a 3 day pack. Made of what appears to be a mid-weight strong nylon (Or canvas, it's random), with a rubberized vinyl bottom to allow for being set on the wet ground.
Wz.93 Pantera camouflage is a great pattern that's highly sought after for its effectiveness and nice appearance. Straps are adjustable. Most of these appear to be unissued, but please allow for some wear and color variations of the bottoms (all some shade of green, but some are darker/lighter etc.).
Overall, a great ruck at a great price!
