I bought this jacket for my boyfriend for Valentine's Day because we were having a record cold winter in Pittsburgh and I didn't want to expose him to hypothermia gets whenever he has to work outside in sub-zero temperatures, but I didn't find any coat I saw him wearing warm enough and I wanted to get him a jacket with Omni-Heat reflective lining like my Lay D Down jacket (it saved my life in this winter). I gave it to him early for him to try this week and he said it would definitely keep him warm in freezing to single digit temperatures without overheating like he did with one of his other coats, he just felt that way probably like he was outside on a nice day and the size XL fit him perfectly so I definitely made the right choice for him with this jacket and I think he will put it to good use especially when our winters stay so cold !
