You might have seen the Um Tote that was designed back in 2005 that took a single piece of industrial felt and zipped its way into a bag. Actual, led by Josh Jakus, has released their latest design, the UM Pack, which is larger than the Tote and comes complete with a shoulder strap and side pockets.
The concept remains the same – the ability to create a container using one piece of felt and a zipper. The design lays flat when not zipped up making it easy to travel with.
