Impressed
I’ll be honest, I didn’t have the highest expectations for this jacket. However, I very pleasantly surprised by the fit and quality. The jacket fit very well and just as I expected. The quality was even more impressive with the weight and overall quality of the denim. For the the price, this jacket definitely hits all the marks. I was able to style it perfectly with a hoodie.

A timeless classic at a great price
This is honestly a very well-made denim jacket, with all the classic features found on a Type III Trucker Jacket: 2 breast pockets, 2 side pockets, 2 inner pockets. The material feels very comfortable and thick and strong at the same time. A multi purpose jacket that will be your perfect companion for almost all seasons in almost all situations. I took an XL size because I wanted to wear a sweatshirt under it. I weigh 198 pounds and am 5.7 tall. I will probably buy another one in L size for a tighter fit.
