On hot days, your vehicle’s air conditioning helps you and the front-seat passenger(s) stay comfortable. That might not be true for those seated behind you, however. The Noggle was designed to help by directing cool air in summer (or warm air in winter) to the second or third rows. The colorfully designed flexible hoses attach to one of your air vents without the need for tools. Noggles are available in six-foot lengths for forward-facing passengers, eight feet for rearward-facing infants, and 10-foot-long versions for minivans and utility vehicles with three rows of seats. Prices start at $40. Make your selection at www.nogglenation.com.
