Thermolite vs Merino

I have a decent event jacket I did the 24 peaks in - even with merino base layer I sweated like a rapist (and it was properly cold)..... honestly can't tell the difference between event & gore-tex

ahhh, that's probably because you didn't do it in a Paramo...

having had eVent (most breathable and previous bike favourite), XCR (tough as nails, great for climbing, especially in granite chimneys!) and PacLite (stashes away as my backup jacket for hiking/climbing but sweat fest when cycling), Paramo is the most breathable yet.

right, back to bike radar...
