Charging up hot a climb seems a little less like torture with the mesh-paneled, short-sleeve Craft Active Jersey helping to regulate your body heat.
Upper chest / arms / neck area are a little tight, but then I did order a size small. I am 5'6" 170lbs. Fit is snug, but not the compressed feel of a race cut jersey. star deducted due to the color. I thought the blue/white with fluoro yellow accents looked cool. When I tried it on it reminded me a little of an early 1990's windbreaker color. Not the manufacturer's fault I'd say, more my computer screen probably. The blue is almost a teal. Rock the grandma power-walker look.
I'm 5'11, 180 lbs, large chest and shoulders. Ordered a large - it fit well everywhere except around the neck. And I don't have a small neck - 16 1/2". Not sure what the hell size neck they designed this one for. So back it went.
