Worth the money? If you are someone who’d buy a KH frame over a Nimbus to save weight, then yeah they are worth it. I don’t hit my knees, so I don’t know about the 3D knee pads, but I assume they hook together with velcro.
I just scoped out a video on 661’s site and their shin pads are essentially the same as 661’s “Evo”. I’m wondering which is better. 
I wear both the Knee & Shin 661 EVO d30 pads
They don’t but it’s never been a problem for me. The “meet” and sometimes “overlap” just below the knee.
To the OP - If you want the best and money is no object, go for the POC pads! I got the POC Joint VPD Elbow and love em! Those really breathe! I will buy the POC Joint Knee/Shin when my 661’s wear out.
wow iv just seen the price 
they need to be something special over the kh and 661 to be worth twice the price dear santa can i have 
Unirox, is it true that you can take those apart and use them separately?
Just got my hands on the 661 Evo shin…not impressed. The pad coverage is very minimal and they run a bit small. 
Now to return these and find something else.
What’s that, the Evo shin’s? My biggest complaint is that the padding is only on a small portion of the front of the shin; not the side or fully covering the strike area from top to bottom. Am I expecting too much or were they designed to be fairly minimalistic? I mean, they fit very comfortably…especially compared to my old Hammer 2Z’s.
That person is a spammer or a bot. Look at their sig.
But on topic, aren’t the evo’s really hot?
I have no idea…I haven’t worn them. They seem like they’d be very breathable though because there small breather holes all in the front. They fit great, run a bit small, but the coverage in the front really isn’t that impressive. I’m tired if shopping around for the “perfect” shin guard that I may just keep them.
Six Six One Moto Shin Guard
I had forgotton that I had some 661 shin guards I bought for ATVing and I tried them and they are great. They offer much better knee protection than the 661 4x4 guards and since they are open back and a bit shorter they are much cooler. I also find that they stay put and I forget tI have them on. here is a link. They are actually like a 3/4 length size. They also have some flaps on the sides that appear to offer some good protection to the sides of the knees.
I have the fox version of them and they ok not great tho
