Mini review: Trek Circuit Pro bib shorts review
The Circuit Pros caught us by surprise. They appear to be fairly run-of-the-mill lightweight bib shorts, but try them on and you feel them come to life.
The thin 200g Lycra makes them a bit delicate but very comfortable, especially in warm weather, even if it is at the expense of being particularly compressive.
The leg grippers hold well and mesh bibs stay put and vent well; the legs themselves are slightly longer than usual, which you’ll either love or hate.
