• possibly a dumb question, but the last few times I’ve been riding with the pertex jacket stuffed into the back pocket of my bibs, I keep having the thought that the sweat transfer onto the jacket can’t really be doing wonders for the waterproofing coating on it, and that maybe I should avoid carrying it there for long periods of time.

    Does that seem about right or is it not a worry? @Chopsicle

  • Assuming Pertex is similar construction to Goretex, sweat and oils can cause delamination of the layers. You definitely want to be washing the jacket regularly in a tech wash.

  • Pertex-with-no modifiers isn't similar to Goretex at all, and neither IIRC is the Pertex Quantum used in the wind jacket. The worst thing likely to happen to these is that they won't breathe well if the weave is clogged with oil, or they'll wet out faster if the DWR is affected.

    The Pertex Shield in the rain jacket is 3-layer, so could possibly delaminate.
