Billwrote a review of ION K-Pact Zip Knee Pad on June 1, 2018
Familiarity: I've used it several times
I've had the POC DH 2.0 VPD etc, etc... They were pretty good, not great because they fell down a lot. These ion pads do not, they stay up...period. The zipper was something I opted for and wasn't sure how I would feel about it. First time I wore them the zipper bothered me, after that, they've been mint. I love these things and I think they have pads on the side of the knee which is also awesome because I think I used to hit that on flow/jump trails a lot and didn't realize it (I'm learning). The ability to take them off and drop my stuff in the car easily (because they unzip) and go grab a beer, also cannot be measured. Love them so much I bought the elbow pads too. One thing I cannot say is how long the zipper will last, but if it does fail I'd opt for the non-zipper version. I read an article about these being the best rated knee-pad and in my opinion they are for downhill/aggressive riding but I wear them always.
