Thermolite vs Merino

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...

I agree, Paramo > *. It's the choice of certain mountain rescue teams for a reason...

want me to sort a group buy for some bwahaha :-)
