“The material on the M3 jerseys is very lightweight and perforated to enhance breathability. Very comfortable to wear and the construction seems to be good. Definitely a warm weather jersey. Great color offerings. The price is pretty decent if you can get them discounted. I am 6'2" and weigh 195 lbs. 42-inch chest and fairly strong build. The XL fits me perfectly. I can squeeze into a large but don't feel as comfortable in the large as I do the XL. I own several Siroko products and consider them to be quality gear that is pretty affordable. Recommend!”
