I've been on the look out for a small day bag to use during my travels. It has to be discreet, durable and not break the bank- This one by Porter and NEIGHBORHOOD at least fulfills two of those points. Made from a lightly quilted nylon ripstop- similar to the linings of old military coats it should be able to handle what ever you throw at it, as well as develop a nice vintage aesthetic over time. Since it's a collaborative issue the run is limited, so you wont see too many of them out there either which coupled with Porter's top notch quality are strong selling points for me. Available now in black & olive on END's webstore.
