‘@angeldust It just allows me to go a bit colderer. Sometimes I’m plodding with a local group and need a bit extra. I know it’s already wind proof adding a thin Pertex layer gives you a few more (less) degrees.’
Interesting. Any thermal advantage you get from a pertex windproof will be from er, keeping the wind off, so I would have thought any additional insulation advantage will be very minor. A guess it will make *some* difference though. If it works for you, why not!
A more breathable solution for the same warmth might be a fleece jersey/baselayer under a single windproof layer. Might have less (or at lease different) flexibility though. Personally I’m not a huge fan of pertex on the road (unless it is very well fitted), as it’s a bit crinkly and noisy.
