If you're looking to buy a bag, or are designing a bag and need to see a wide cross-section of product for inspiration, check out Rushfaster. The Australia-based online retailer (located in Glen's hometown of Sydney) is like that friend you have who's a bag aficionado and has a closet full of only the best stuff.
Rushfaster offers a heavily-curated selection of brands from around the world—Booq, Gravis, BuiltNY, InCase, Mandarina Duck, Superdry and more—and stocks every conceivable permutation of bag and carry-thing: Laptop bags, luggage, messenger bags, backpacks, wallets, iPhone and iPad cases, you name it.
If I was working on a bag design project, browsing Rushfaster's site would be my starting point; but for those of you just shopping, as of today they're having a 60%-off sale. (Glen demands I point out that prices listed on their site are in Australian dollars. While most of us know those are the same thing as American dollars, Glen insists they're different.)
