Hello experts. I'm on a search for the perfect carry on garment bag for my son. He carries a cello, rollerboard, and personal item onto the plane. Because he has an extra seat, he could bring another carry on item. I have in mind a tri-fold that will slip over the rollerboard handle. Tumi and B&R are out of my price range. Any suggestions? Or other ideas about the best way to carry his gear (I have also considered going the other direction--a new rollerboard that will carry a suit with an underseat that passes over the handle).
Here is what my internet search has uncovered. Does anyone have experience with any of these? A. Saks Deluxe Expandable Tri -Fold Carry-On Garment Bag
Victorinox Werks Traveler 5.0 WT Porter
Mercury Luggage Executive Series Tri-Fold Garment Bag (which doesn't look like it has a great hanging system)
WallyBags 52 Inch Garmentote Tri-Fold with Shoulder Strap (attaches to the top of rollerboard handle via velcro rather than passing over the handle to rest on the luggage)
Thanks for your help!
