Hey guys, I have been kiting for about 5 years, starting about a year ago, when I'm riding overpowered (I like to boost) after about 1h I start to feel pins and needle in my back around the edge of my harness (ion riot), and I have to try to bring it back down or move in it to have the feeling disappear, but from there after each jump I'll feel it.
Any one had the same issue and know the cause and/or solution ?

I used to ride a seat harness before so I'm wondering if the harness doesn't fit me (it feels comfortable to me though) and I should try another model or switch back to a seat harness.

Try a different harness if you can?

I used to get a pretty sore back with my old ion harness, decided to splash out on a Mystic Warrior and couldn't believe the difference.

Turns out not all harnesses are created equal

+ 1 for harness change. I too used to get a sore back from my ion harness. Switched to mystic, instant fix.

Yeah I'm considering switching harness, I tried a mystic stealth but it was very uncomfortable, maybe ride engine would fit me better, else maybe back to a seat harness.

Just go for a top of the line one instead of a lower or mid range and see how that treats you. I heard the Majestic X was even better than my warrior, but it cost another hundy so I cheaped out, but its still better than the nasty little hard shell thing I used to use

The ion I have is already top of the line
