Nike is the one of most biggest brand in the world.Everything they launch is the greatest item iyself, I brought Nike duffel bag 3 years ago and I used it everywhere whether it tracking or any other trips.From laptops to clothes I put everything inside that bag and now its has been 3 year and thier is not any single scratch on that bag.Its like it will gives me 2 years of more service .if you buy anyother companies duffle bag it will start torning from the lower part because every time we put bag on the floor it will get effected.so if you want to buy laptop bag or any other bag , go for nike bags they have completely different variety which gives you better experience.
