As far as telescoping-handled rolling suitcases go, Castelli's Rolling Travel Bag has all the standard mobility and storage features covered. Its material resists water and stains, it has multiple handles for all angles of carrying and hefting, and the two main compartments are further divided into sub-compartments to keep your base layers separate from your casual clothes and bibs. Castelli finishes the bag with a few welcome details that help you get from home to all manner of exotic start lines with your kit intact, including a fleece-lined compartment for your head unit and skid plates and a reinforced bottom for armor while bouncing over curbs and supporting oversized carry-ons after being stowed. As an afterthought, Castelli also opts for low-density, low-noise wheels, which means your passage won't interfere with the dozens of hands-free cellphone conversations from the people waiting in line at the chain cinnamon roll restaurants in the terminal.
