I have the Journey Shorts and Pants in charcoal. I attend power Vinyasa flows at Real Hot Yoga and Yoga Six in Johnson City and Knoxville, TN seven days a week.
The fabric is incredibly lightweight, flexible enough for all the inversions, stays in place (important!!!!), wicks sweat very well and seem to wear well. I would recommend handing them to dry as the drawstrings fray otherwise. I'm not a fan of the copper bands at all, but the knots in the drawstring holding them are easy enough to untie.
