I can proudly mention that I've seen my fair share of luggage varieties over the years.
For my 'apprenticeships" with various hotel & travel management positions & personal travel for the past decades there are good & bad characteristics in every style, shape, colour & brand of luggage.
From my own experiences & observations, consistantly & contentiously .. Samsonite seems to be the front runner & distinct innovator in this game..
Forget the cheap 'price leader, look a like type" it will certainly let you down at the worst possible moment.. & embarrassment galore!
As my own travel requirements, I use a Rimowa Topas - which without bias or any sponsorship or donated deals.. Self funded variety, with my hard earned 'clams"... It certainly serves all of my travel exceptionally well.
This is a full alloy, made in Germany, completely sealed, hard case, unladen @ <5kgs. Brilliant locking system & the best rolling system over soft/hard/uneven surfaces.
This has endured this most harshest treatment in airline baggage handlers, railway & shipping experiences, along with extreme weather conditions, snow & heat, & has come out relitvely unscathed, with just a few souvenired dents & scratches..
So, without compromising on quality, for a wonderful all round versatile case, have a good look at these, then if budget does not permit, work your way down to a Samsonite., or similar quality.
I know this is a bit of a rant.. But always consider the 'precious" contents of your luggage- if you value these! , & invest in a substantial piece of equipment that will last the distance.. Have fun travelling!
