I bought both the 187 Killer pads and the Triple 8 KP22 Knee pads to compare. They are both good pads, but they both have upsides and downsides. For the 187 Killer Pads, the upside is they are quality construction and I believe they would provide a lot of protection in a fall. Padding is thick and adequate, if not a bit stiff. I would have liked to see a little more pliable padding, but I imagine that would require even thicker padding, making the whole pad thicker and bulkier. This brings me to the two downsides, which are related. The 187 Pads are bulky... bulkier than the Triple 8 pads, which is probably due to the extra padding sizes. The 187 pads have a bit more padding, making them bulkier. In addition to the bulky pads, the Large (which I purchased) was too tight. They were almost impossible to get on (and take off) and severely restricted my movement. There's no way these would have fit over my jeans or anything thicker that I would normally ride in. The Triple 8 pads did not restrict my movement in any meaningful way and did not cut off my circulation, and were easier to put on and take off. While the 187 Killer Pads might offer slightly more protection, the convenience of putting them on the and the lack of movement restriction, and slightly less bulkiness make the Triple 8 knee pads superior to the 187's. If you want the ultimate protection and don't care about your movement, then the 187s might be a better option, but buy 2 sizes up... the knee are sized WAY too small. In the pic, you can see The Triple 8 on the left and 187s on the right for the knee pads. My movement in the knees was SEVERELY restricted on the 187s, whereas the Triple 8s did not restrict my movement at all. I think the 187 knee pads would offer a bit more protection in a fall, but at the cost of movement, the difficulty of putting them on and taking them off, and them being too tight, there's no way I could recommend them. I'll be keeping the Triple 8 and sending the 187s back. I would like to have liked the 187s more, but the sizing made that impossible. Perhaps with a larger size, I might feel differently, but I think the movement restriction would still be there, given the bulk of the 187s, making it a non-starter for anything that requires movement in the elbows and knees.
