I spent days researching sustainable jackets with ethical down fillings, so that I could find something that would keep me warm, because I REALLY feel the cold. I then spent days battling with myself over spending £190 on a jacket. Well, it is one of my better investments. The jacket is so light, but it keeps me scarily warm...it's almost magical. I'll definitely be buying Berghaus again next, when I wear this jacket out. Take my advice, if you want a quality jacket that will keep you proper warm, buy the men's Finnan 2.0 Reflect Down Jacket; strong coastal wind doesn't even permeate it. Thank you, truly!
