I ma looking at buying a good duffel bag. Approx 20 x 10 x 10 or perhaps 21 x 11 x 11. It must be made from the best fabric and I would prefer 1050D ballistic nylon. Can members recommend a good duffel bag. Preferred colour is black or anything dark. Warranty is important and approx budget is USD 175. Victorinox has some good duffels. Can members suggest anything on the materials they use. I guess they use 420D (3 to 4 threads together and twisted) and not 1050D.
