Yes. Good suitcase though. >>2338327
It depends on the type of travelling you're doing. I've travlled for a month with only a carry on and I also checked a rimowa trunk for a week stay in Paris. Difference being that it was winter and I was going to upscale places everyday. So I had to bring two suits, sport coats, overcoat, shoes...
But yes, usually a carry on is enough for any trip.
