Travel bag recommendation 30-35L

I recently purchased an Aer CPP2 backpack as my first backpack and I love the build quality and aesthetic. It’s a great EDC for me but now I am looking for more of a travel backpack for 3-4 day trips. I am looking for a travel bag recommendation for 30-35L. My first thought was to get Aer TP3 ultra, but does that make sense?
