When unpacked, the Matador Daylite 16 is surprising spacious. It has a 16 L capacity large pockets on the side for your drinks or anything you need quick access to.
There’s also a deep front zippered pocket big enough for a map, passports, sunglasses, and more. The zippers are water resistant so your stuff are probably safe in the rain.
The Daylite 16 is mainly made of waterproof Cordura fabric, which is light and thin, yet very tough. The shoulder straps have a breathable mesh design.
