Japanese bag brand Porter has made another pet product collaboration – this time with super-cool pet product design studio Flavor. Porter’s previous collab effort of a dog collar from streetwear designer Original Fake turned into a big hit. But this time around Porter has gone to their strength (bags) and designed a innovative dog carrier for the urban pup on the go. The “Dog Ruck” is a high quality backpack carrier made out of water repellent cloth and reinforced with double stitching. The interior includes a lead hook – to prevent unexpected jump-outs – as well as a padded bottom for the dogs comfort. For the smaller dogs there is also zipper netting to contain your pooch while out and about. While I don’t think I would hop on a motorcycle with my dog on board this way – it does offer a much easier method for moving around a city or traveling short distances. Currently the Flavor x Porter Dog Ruck is only available in Japan and it costs $460+USD (52,000 Yen). But with the ever expanding pet fashion marketplace in the US and Porter’s interest in producing cool dog products – it is only a matter of time before they make it to North America and Europe.
