I've used the Aero Hex a few times now, and I really like the look of it! The fit is also solid, for the most part. My complaint is that I'd like the shirt to be a little longer. I'm 6'4" (193cm) and 215lbs (97.5kg) or so and got a 2XL. I often have to pick between shirts fitting too short, but properly across the chest, or baggy across the top but the right length. In this case, the bottom of the shirt barely overlaps the matching shorts (aero tri 9") and I wish that it overlapped a little more.
I'm relatively new to triathlons, though, so maybe this is the intended fit.
