I was looking for a lighter hoodie for the spring and saw some positive reviews on Youtube about WYR Wear. I decided to give it a try and ordered a medium-sized sage-colored no sweat premium hoodie. For reference, I'm 5'7", 165, 40.5" chest, and 32" waist. The medium fit spot on right out of the package. It did shrink a little upon washing, but, still fits well. If you're in between sizes you may want to size up. It's very well made and surprisingly warmer than expected. I wear it a lot working from home and when I have to run out I just throw a bomber jacket or vest over it. I'd definitely order future products from WYR Wear.
