Yes, I personally find it ironic, especially for the price, but they are not certified still (you can check pretty much any Internet shop selling them, you'll see they are not unlike Airowear, Woof, CO, RP, etc.). The reason people use them is because they are so light, flexible and comfortable. Until quite recently most certified vests felt like you are packed in a box and/or restricted in motion (and for some people even newer ones feel this way). With newer technologies it's not a case anymore really (say, Airowear is very comfy, Woof (I have one) doesn't feel like a box either, I've heard RP is really nice as well but I never had a chance to try it).
