Wolffepack

Convenience and safety are this pack is all about. It is worn as the usual backpack but it has a cord which you can release and the pack will swing to your front without taking it off. The main shoulder straps are still on. Once you are done taking your stuff inside, you can pull the cord again and it goes to your back.

There was a question on one of its review about how heavy it can carry. The website says the cord can handle up to 300 kilogram so that is pretty tough. Plus, it has different designs for different purposes so you have different options to choose from.

See this video to appreciate its features. The video was made when the founder was requesting for crowdfunding years ago but the Wolffepack products are now in the market.
