Phat Phredwrote a review of Gore Bike Wear Power Thermo Bib Tights with Chamois on January 3, 2012
Very comfy--no bunching in crotch. Legs are long. Stirrups hold tights down. Nice pad. With toe covers I'm wearing booties less. The highlight is the double layer of material starting on the lower thigh, covering the the knee and some of the shin. It doesn't restrict motion and keeps my knees much warmer. MTB in near freezing temps comfortably. Road ride comfortably to low 40's high 30's. The medium fit me fine (32" waist, 34" inseam, 175#). They don't get clammy like windstopper does.
