3DCOC size - try turning the 3DCOC inside out. Aesthetics change, but 3 things happen - vertical size improves significantly as the oversized seams are not robbing interior volume, the bag can stand upright by itself as the seams act as stabilizers, and the bottom of the cube becomes flat allowing bottles and items to stand upright on a flat surface vs balancing on the seams. Lastly, the 3DCOC product page is confusing or just dimension-fluid. The listed external dimensions equal the internal volume capacity 61 cubic inches = 1 liter. The product page also lists volume being exactly 1 liter / 1 quart, Today I Learned, never knew liter and quart were equal lol.
I personally feel the 3DCOC is due for a refresh. In keeping with TB looks and achieving the inside out 3DCOC benefits, I would like to see the 3DCOC match the style of how the Original Shop Bags are sewn. The large side panels and bottom are the same piece of fabric and then the seams are only on the sides allowing a flat bottom that allows bag to stand upright while maximizing volume. A strip of halcyon or ballistic fabric would be stitched to the bottom as a wear surface over the clear material.
Aesthetics. To each their own. You are buying a designer's designs, his name is the company, he does his design until he retires. Buy what makes you happy. Plus, if the business is selling enough to pay all its employees a real living wage for that city, why change and bravo to them.
Removable straps mentioned in this thread. Looking at getting an A45 or A30 in the future. Reading through the forums it is occasionally mentioned people cut off the straps of their aeronauts to save weight or utilize the space. Why can't the aeronaut straps attach at the top by removable system such as gate keeper straps? I would assume a clasp that would not dig into shoulder is available or engineerable. The straps are non permanent at the bottom, thus far fetched to do so at the top. Would also allow strap options (normal, light, heavily padded)
