Great thin midlayer,almost a baselayer; extremely comfortable and surprizingly generous for a Mammut, but it is not too big. Mammut says it is a slim fit which must be roomier than an active/athletic fit but smaller than a regular fit. I am usually between a large and an extra large with Mammut. This large fits great. The 10% elastane certainly helps here, but it is not just that. The new ones will have side pockets which I miss, but I still think it is a great jacket. After I saw how nice it was, I bought one for my daughter
