Airsoft GI now has the HSS knee pads in stock... "The HSS Knee Pads are some of the most comfortable and durable knee pads available. There are four straps total to secure the knee pad to the wearer, two above the knee and two below. The knee surface is made of hard plastic to protect the wearer from feeling any BBs or other objects they might kneel down on. Behind the plastic is a thick layer of padding to absorb the impact of kneeling down quickly. All of the straps are held together with Velcro so you know they won't come off during use."

What they have in stock are those in ACU and Tan colours.
