Hubby and I used the Tom Bihn Aeronaut and Tristar for our 3 day/2 night trip this week - they were fantastic. The Tristar is probably fine for a 3 or 4 night trip but I will definitely order another Aeronaut for those time when hubby and I will both be traveling for a week. I have also decided that I like the look of the Black/Iberian look. Haven't decided if I will get the Aeronaut in Steel/Solar, Black/Iberian, Steel/Ultraviolet, or wait and see what the new colors are that they are supposed to be announcing. I don't have a long trip until late April so I still have a little bit of time to decide. Of course, I still have the Red Oxx Airboss coming... maybe I could pack for a week in that since it is slightly larger than the Tristar. And, oh yeah, I love packing cubes!
