An Ultra Compact Gym/Work Backpack

A backpack that can fit your office essentials AND your gym stuff – including a pair of shoes – without extra bulk? AER does it right. And it's even more compact than the Duffel Pack 2!

The Duffel Pack 3 features separate compartments for your gym essentials and work stuff to keep you organised throughout the day, and improved features from the Duffel Pack 2 such as a more breathable shoe bag compartment that can be converted into regular bag storage if not needed.

At only 1.3 kg for a 21.4L capacity, it is super light. Made of military grade 1680D Cordura® ballistic nylon, it boasts hyper-durability like no other.

Stylish and functional, the Duffel Pack 3 is a versatile backpack. Go from work to gym and never look out of place.
