The Best Modular Backpacks

If there’s been a trend in the past few years, it’s been modular design in carry. But what exactly does ‘modular’ mean? In essence, a ‘modular’ backpack features a range of smaller parts or modules (such as pouches) that can be used in tandem with the primary bag. The key benefit of a modular backpack is adaptability. Add modules you need and remove ones you don’t, allowing you to tailor different carry setups to different loads and environments.

In addition to the separate modules, modular design also encompasses the means by which those modules (or other gear) are secured onto or inside the bag. Think webbing, magnetic buckles, O-rings, Velcro panels and more. The possibilities are kinda endless.

And when you really get down to it, there’s two variations: external and internal. So we’re going to explore both below, and give props to the brands pushing the envelope and doing it well.

External modularity

The origins of lacing and latching modules to the exterior of a pack stem from the military’s MOLLE and PALS webbing. And nearly every ‘tactical‘ pack you’ll spot will have PALS webbing somewhere, so below we’ve chosen pieces that have done it best, and/or differently, with brands and designers introducing modular design to photography, fashion and everyday use. And those pushing past the criss-crossing of PALS and moving to magnetic connections and fully modular harness systems.

Y-3 Multipocket Backpack

The Y-3 Multipocket Backpack merges clean streetstyle, minimalism, and functional modularity. The bag offers multiple exterior pockets that can be removed and used internally as organization pouches or separately from the pack.

Internal modularity

Internal modularity also originated in the military with medic bags and first responders, folk who needed to carry a lot of gear, in varying formats, and access key items quickly. But now it’s commonplace in travel and everyday carry pack loadouts. In reality, any pack can have internal modularity with just the addition of pouches, but we’ve chosen the below because they’ve taken it a step further, and not only built-in internal attachment points and specialized pouch quivers, but entire modular ‘systems’.
