Chris Lamontwrote a review of Zero RH + ZeeKey Bib Shorts on August 9, 2013
Familiarity: I've used it several times
I've used a number of other product including the Castelli endurance and aero race with proghetto x2 pads, Gore Ozon, but these became my favorite short upon 1st wear.
Pad is comfortable, but it's all the finishing touches that really make this short great (gripper and elasticated bib straps). The babric is really quite good and overall comfortable.
Sizing on these is european, fits just slightly smaller than Castelli even (not a size smaller, just snugger). So take this into account rather than getting your normal size in huge-fitting north American brand gear.
