Thanks for your responses. The only thing that puts me off with 511 tactical is that it looks too tactical. Not sophisticated in design. Too sporty.
MellonC - yes, the BR weekender was on my list but when compared to Victorinox, lags behind in price and lack of compartments and scores big on build, fabric and warranty.
Victorinox still makes some nice sized and designed duffels. Their fabrics are still unknown. The Avolve 2.0 which I like is reasonably priced, and used 1500D Tedeolon. Never heard of this. Can someone shed light on this?
The WT mentioned uses 1252D high twist which I guess is 3 threads of 420 twisted. I did see a video on youtube of this duffel. It is difficult to maintain shape as mentioned by "gobluetwo".
Victorinox does not mention fabric on their American website. On the Indian website they mention fabric. Very strange.
