This is such a popular item . We.ve added two more bags. This one is OLIVE GREEN color.Each backpack is hand embroidered and beaded on microfiber (microfiber looks and feels like suede but is light and synthetic and almost indestructible-you can wipe it off, it is the same stuff as couches are made from). Outside is brown or black with red piping around the oval bottom. Inside is lined with waterproof red fabric, with just the right zippered pockets for change and other valuables, a clip for keys, and a pocket for cell phones. Inside flap has zippered pocket, and outside back also has a zippered pocket, hidden and out of sight. Closure for the backpack is a double zipper, for easy opening. The backpack is "gussetted", so that when opened, there are sides to prevent stuff from falling out. Straps are adjustable, with the clips made from natural animal horns (taken after they have died). All our products are made in small workshops outside Hanoi (you can get more info in the "About Us" section. We donate 10% of profits to Tamaryn Fund for Good Deeds. This winter was the coldest winter in northern Vietnam in 20 years, some of the funds bought blankets and clohting for kids in orphanages, which my daughter Tam (company CIO) and I helped distribute.
