i ordered the top and bottom set but for some reason was sent this one instead. There are minor differences i noticed in the pictures, below the waste doesnt have the green material as well as around the knee pads, it is kryptek cammo all over. Also you can cover up the knee pads with a krpytek velcro flap on the inside if you want. Not sure which one is better, i assume different generations. The small size is a 30x32 for anyone wondering. I have a strange body type (29x34) and these are the best fit for me from general sizing, however because they are slightly short the knee pads go above the knee cap instead of staying under when i kneel, so my knee is only protected by the soft pad instead of the hard pad. Make sure you order a larger size if anything, BDUs are ok when baggy as you will be moving around a lot in them. The more i checked the pants as i was wearing them the more cool features i was finding, it has an elastic band with velcro tabs to tighten the waste without the need of a belt. There are zipper back pockets, normal hip pockets, 2 sets of pockets on each thy, 1 pocket on each calf. There is an adjustable elastic band behind the knee to pull the knee pad tight and make it less baggy. Also velcro straps around the ankles to tighten it around the boot or ankle. I should be getting the top tomorrow and will do a review of that on the top and bottom set.
