As of 2018, of the 22 collections in Tumi's current line-up, 12 of the luggage collections do not have leather monogram features.

Those collections include:

Arrive, Ashton, Beldon, CFX, Georgica, Harrison, Mariella, Monaco, Nassau, Province, Stanton, and Voyageur

I'm assuming, since schalliol mentioned his luggage from 16 years ago, that is still the original Tumi "Alpha" line.

Tumi was also in its end phase of shifting manufacturing operations from "Made in USA" to its Chinese factories.

Tumi did not start aggressively adding seasonal collections until 2006.
