I’ve got a set of VPD 2.0 Joint’s and they’re my ideal all-day pad. Wearing them in a Basque Summer got them sweaty and they got a bit salt marked by mid week, but rinsing under a cold tap and air drying fixed that. They didn’t get chafey at all – the only time they have chafed at all was once I tried carrying them in my pack and putting them on at the top – and that’s cos my legs were a little muddy by then so not the pad’s fault. I’d just put them on at ride start and take them off at end now because of that and they don’t bother me at all. They do a good job of staying put while crashing.
Just after I bought mine, the VPD Air’s launched and I wondered if I’d overbought, but this doesn’t seem to be a problem. I’m not a heavy sweater generally though, which is probably relevant.
