The promised characteristics (breathable, waterproof, windproof, ...) are in practice all met. The jacket can be worn both in the fall and winter. At no time was I was too cold or this.
It is handy that the inner jacket also cut out quickly and can be worn separately, for example. Thus, the product basically consists of 2 jackets (inner fleece jacket and outdoor function jacket with CEPLEX membrane). I wear the double jacket usually with the inner jacket and can not say anything negative about the function of breathable Ceplex membrane.
The jacket is concerning. Possibly be described as generous in size (length, etc.). Hence my recommendation in doubt between 2 sizes would not necessarily choose the larger.
Conclusion: If 3-in-1 style is looking for a reliable function jacket (2) with good price / performance ratio, makes nothing wrong with buying this jacket. I can only recommend this functional jacket in every respect.
