Power walking with 1/2lb hand weights
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.
