There are a lot of gadgets we think of as “everyday carry” (EDC) gear—phones, first and foremost, but also laptops, headphones, and battery packs, to name a few. But while a lot of us routinely carry around a laptop or tablet to get work done wherever, most of us leave our mice at home, content to rely on a less precise trackpad or touch screen. Logitech’s newest mouse, the Mobi Fold, might get you to reconsider that approach.

It’s an ultrathin, ultralight “travel mouse” with a hinge in the middle of the palm that literally bends the mouse in half when you aren’t using it. Folded shut, the Mobi Fold is about the same size as a pair of earbuds, so it easily fits in a jacket or jeans pocket. After testing the Mobi Fold for the past few weeks ahead of its launch today, it’s far and away the best travel mouse I’ve used, especially for folks who care deeply about traveling light.

The concept of a “travel” mouse that’s made to come with you on business trips and workdays at the local coffee shop is not new. Mice like Logitech’s own pint-sized MX Anywhere 3S have been designed to cater to folks who want to maximize productivity while working away from the office (or home office). But, while portable to fit comfortably in a small bag or briefcase, travel mice almost always come with some serious compromises. The biggest issue for me has always been that their “mini” compact builds usually compromise their ergonomics, making them less comfortable to use. Rather than filling your hand, a small mouse will force you to squeeze in and grab it, flexing muscles that will eventually tire or even cramp over weeks, months, or years of heavy use.

The Mobi Fold fixes that. Folding the body in half brings the form factor down to 2.25 wide by 2.5 long by 0.75 high inches. I’ve been toting it around for a while now, and it fits easily in my jeans, even though I already carry an iPhone 17 Pro (and sometimes a second phone for testing), keys, earbuds, and a slim battery pack. But, perhaps more importantly, the unfolded version is a full-size mouse that fits decently in your hand. Measuring 2.25 by 4.75 by 0.3 inches (at its thickest point), the flattened V shape is a bit narrow but allows your hand to drape over it naturally without making you squeeze to get good control.

As far as functionality goes, the Mobi Fold is pretty no-frills. You get the standard right and left click pads and a central touchpad in lieu of a scroll wheel. Given how thin it is, there’s no room for scroll buttons on the side here. You can, however, remap the touchpad from scrolling up and down to other functions via Logitech’s configuration app, Logi Options+. And the mouse does support Logitech’s smart switch feature, which allows you to pair it with up to three different devices via Bluetooth and hot-swap among them with a small button on the underside of the mouse.

Personally, I feel less productive without a mouse. In the field on a reporting trip, noodling with notes at a coffee shop, whatever the project is, I’m just less agile with a touchpad. Having a mouse on me all the time—at least whenever I have my laptop or my tablet—makes a lot of sense.

Obviously not everyone feels that way. And, at $80, this is clearly a bit of a splurge for frequent fliers and mobile workers who want a mouse specifically for when they’re away from their desks. And obviously adding a new piece of EDC gear to your kit is always somewhat fraught—more bloat, more weight, more things to forget—for the true digital nomad. But the Mobi Fold could make it easier to get comfortable and lock in when you can’t have your full toolkit on hand.
