Canadian-style slotted military buttons - These are used for the waist and rear pockets.
Zipper fly - A Delrin-tooth YKK zipper fly for convenient donning/doffing and a military-style taped tan button waist closure.
Seven 2.5" belt loops fit rigger belts (shown here with a Liger gun belt).
Two ITW D-ring keepers on front belt loops - you can dummy cord front pocket items there or clip keys to them.
Double reinforced seat and diamond shaped gusseted crotch as found in rock climbing pants for free range of motion.
Double reinforced knees with tailored articulated darts - these are the same as on the Legionnaires; they don't have a compartment for knee pads.
All pockets lined with long lasting self fabric instead of lighter material
Two front welt pockets - probably my most used pockets for sunglass case and cell phone. They're 6" deep and 4.5" wide with a 3.5" opening.
