For a blazer, its super light and its breaths easy (good for the people who get hot super easy like me). I do love this blazer overall. My only issue is my shoulders are too big. If I got the one that fit my body, it'd be super tight for my upper body, but when I got he ones that fit my shoulders, my body felt like it was swimming. My solution was to just bring it to a local tailor and had it tightened up. I understand that all body types aren't the same, so I don't blame the product for that.
