Australian brand 2XU gets everything pretty much spot on with these three-quarters.
They're made from a polyamide/ elastane fabric (similar to Lycra) so they're autumn/spring-weight, with the panels flat-stitched together for maximum comfort. The mesh bib section and silicone leg grippers are bang on and you get both plush cushioning and excellent moisture management from the multiple-density seat pad. The white logos aren't reflective but they're large enough to show up well at night. You're supposed to hand wash these, but life's too short... we used the machine without any worries.
