Tried many brands…..worst being howies…..and all expensive
As a sweaty fellow the material wets out very quickly and when stopped holds little warmth as I cool rapidly, becomes a soggy wet cold blanket.
As for layering well tried it with gore products, omm products and event products not to mention a few windproof brands like pertex.
I have a good understanding of layering systems…..for me wool has a place but not in high aerobic sports for me individuals who sweat buckets.

Oh sealskins have that great big hole in the top that let’s water in
