Yes, I'm a medium in both pants. The old Super Tacks (10+ years old) were roomier and heavier. The Jetspeeds are more form fitting, but there is a lot of stretch fabric through the crotch so I actually feel like I've got better range of motion. I'm 5'10, 165 lbs, w/ 32" waist which puts me squarely in the medium category of most brands size charts.
