WaterField Designs is one of our favorite companies for all things bags, briefcases, device sleeves, and more.

Their latest release is the Mason EDC Pouch, a nimble and modular crossbody bag that’s great for getting around town with — but when the need arises or a greater adventure calls, you can remove the shoulder strap to turn it into a tech accessory pouch that stashes inside a larger bag or suitcase.

Inside the Mason EDC Pouch is an impact-resistant padded foam pocket for an iPad mini (or similar-sized tablet), an easy-access key tether, and enough space and organizational pockets to hold daily essentials like your phone, AirPods, glasses case, wallet, cables, and more.

The main compartment’s dual zipper allows it to be opened from either direction, and both it and the front pocket zipper are YKK waterproof ones that help keep your gadgets safe from the elements.

In usual fashion, you have the choice between 1050 denier ballistic nylon or rugged waxed canvas exteriors, both of which combine with full-grain leather and run for $129 at sfbags.com.
