After the success of its Duffel Pack, Aer expands their line with the Fit Pack and the Sling Bag.

More compact than the Duffel Pack yet still offering the same level of flexibility in carrying your workout gear along your laptop and other work essentials, the Fit Pack is a good alternative for those who thought the Duffel Pack was too large. The Fit Pack can carry most of your gym essentials to even sneakers, while the back compartment can hold up to 15” MacBook Pros for those on the go. The Sling Bag is a great choice for those who only need to carry items for the gym, offering enough space to carry most of your gym essentials. Both are made from the same water repellent polyester material as the Duffel Pack.

You can back their Kickstarter campaign starting March 17.
