Christopher R.wrote a review of ION K-Pact Zip Knee Pad on July 18, 2019
Familiarity: I've used it several times
Just got these yesterday. After looking at most of them it was down to these or the Sweet Protection. Glad I did. The pads are comfortable but if I had to to it again I'd just get the ones without the zippers. The zipper is a pain to get started and keep zipping up so it's just easier to slide them up. The sizing on these and the E-Pact run small. I was told I was between a Medium and Large on both and have to exchange the mediums for a size up. I'll update after a ride today.
ETA: After three of four rides, these pads are good. I got the correct size for the E-Pacts and even Large was a little tighter than I was expecting but manageable. Yeah, they're hot, but it's summertime and 90+ degrees out so I didn't expect anything else. They stay up, provide protection, and give me some more piece of mind on rides. Well worth the investment.
