I use a mec ferrata 2 (schoeller dryskin) or a mission workshop orion (schoeller c-change). The schoeller dryskin has adwr treatment, whereas the orion is fully waterproof w/ taped seams/zippers.
Both are great, huge fan of schoeller fabrics.
I wear a defeet long sleeve base layer with a merino wool sweater and sometimes a sportswool long sleeve jersey underneath the jackets.
