I picked up a pair of Crye Precision G3 pants. They are all weather, durable, breathable, have knee pads, and flexible. They are lightweight and used by the Military in the harshest conditions but can be worn in any season. They are fire resistant and never tear..Why don't more people wear these pants innawoods? Crye G3's are my go to pants now, will never wear anything else /out/.
