I tried ordering Santic 3/4 lenght shorts.
This 3/4 lenght is kinda rare, and i actually like my knees covered just like my running compession shorts.
Santic has few lines of 3/4 lenght shorts, n bought 2 from '5-6hrs ride rating'.
the compression strenght is good. The lenght does go under knee cap, but not quite to upper calf.
but pay attention to sizing chart, as they may advertise as Asian size scale. im asian n i usually wear M, n the sizing is tad tight(butnot quite S).
