What Our Gearhead(R) Experts Are Saying:"I wore the Core Drill Short for a full sprint triathlon and never noticed the transition from bike to run. The fleece liner smoothed things out on the saddle but didn't bunch up or chafe once I started running."A full seat pad makes sense for a long ride, but it's dead weight the moment you start running, and the Core Drill Short skips it entirely. A fleece seat liner smooths out time in the saddle without adding bulk, then all but disappears once the transition zone hits and the run begins. Flat-lock stitching keeps seams from rubbing at any point in the race, while a raw-cut leg with internal silicone grip elements holds everything in place without a hem to catch or ride up.
