JACK1T Men's Cloud Long Sleeve Puffer Racer Jacket

I really like this brand and the lavish design and style but I realize that each 3 of the jackets I purchased are different meaning the way they fit. I normally wear a size L so when I purchase the first jacket I ordered a size XXL because the size chart lists that a loose fitting would fit me perfectly. The jacket fit me to loose so I just kept it. When I purchased the second jacket I ordered size XL and the fit was exactly how I wanted. I decided to purchase my 3rd jacket and order size XL because now I felt that I know my perfect fit and that jacket fits looser than I expected so I’m confused about what size for different styles of this brand. I recommend if it’s your first purchase go up one size hopefully you’ll be satisfied.
