In 15 years of Topas use my carry on IATA has been adjusted once gratis in Honolulu and once I paid for out of warranty repairs in Portland on the check in 29” Topas.
The carry on looks pretty good considering it’s been all over the world and the check in looks beat to .... but awesome IMO.
Just purchased a Topas Business Multiwheel as an upgrade from the Salsa Business Multiwheel.
Wifey loves her Salsa Air IATA. Carry on only and it’s pristine for being a few years old and moderately used.
