A wheeled garment bag is a good choice if you need to hang more
than 3 outfits and/or want the mobility and maneuverability of an upright.
The smallest rolling garment bags usually will hold 3
suits, while the largest can hold up to 15.
Wheeled garment bags can be carry-on approved, however most are too large and must be checked. Some airlines may charge you an oversize fee if your garment bag exceeds 62 inches (length + width + height).
We were looking at Luggage Pros and found a good variety of wheeled garment bags at low pricies.
