Best Travel Case for Logitech MX Master 3S
If you’ve invested in the Logitech MX Master 3S, you know it’s the gold standard for productivity, but its ergonomic hump makes it a nightmare to toss into a crowded camera bag. I’ve seen far too many MagSpeed wheels get gummed up or tensioned incorrectly after being crushed between a mirrorless body and a 70-200mm lens. After testing several shells, the LTGEM Hard Case remains my top pick for its perfect mold and rugged protection.

Best Travel Case for Logitech MX Master 3S: Detailed Reviews
LTGEM Hard Case View on Amazon
The LTGEM Hard Case is the undisputed heavyweight champion in this category. Built from high-density EVA, it offers a semi-waterproof and shockproof exterior that feels incredibly substantial in the hand. When I’m traveling between shoots, I need to know my mouse won’t click repeatedly inside my bag, draining the battery. This case features a precise interior mold that cradles the MX Master 3S perfectly, preventing any movement. The soft velvet lining is a nice touch, ensuring the rubberized coating of your mouse doesn’t get scuffed or shiny over time. It also includes a dedicated slot for the Logi Bolt receiver, which is a lifesaver given how easily those tiny dongles disappear. The zipper is smooth and doesn’t snag, though the case does add significant bulk to your bag. If you prioritize protection over minimalism, this is the one to get.

Khanka Hard Travel Case View on Amazon
Khanka has carved out a reputation for making reliable cases that don’t break the bank, and their MX Master 3S offering is no exception. While it feels slightly less “premium” than the LTGEM, the protection it offers is nearly identical. The exterior is a tough, textured nylon that resists scratches better than smoother finishes. I particularly like the internal mesh pocket; it’s just large enough to hold a short USB-C charging cable without putting pressure on the mouse itself. In my testing, the fit is snug enough to prevent rattling, though there is a tiny bit more “play” than the top pick. For the price, you’re getting a case that can survive a drop onto concrete or being stepped on in a backpack. It’s a pragmatic choice for anyone who wants solid protection without paying a “brand name” premium.

Hermitshell Hard Travel Case View on Amazon
The Hermitshell case is the most straightforward option on this list. It doesn’t have the fancy bells and whistles of the LTGEM, but it gets the job done for a fraction of the cost. If you only travel with your MX Master 3S occasionally—say, once a month for a business trip—you don’t need to spend much. This case provides a rigid shell that prevents the buttons from being depressed in transit. One limitation to note is the zipper quality; it feels a bit more utilitarian and might not withstand years of heavy, daily use. Additionally, the interior lining is a bit thinner, so it doesn’t offer as much vibration dampening. However, it’s remarkably lightweight. If you’re looking for the absolute cheapest way to stop your $100 mouse from getting crushed, this is your best bet.

Aenllosi Hard Carrying Case View on Amazon
The Aenllosi Hard Carrying Case is where style meets function. Most mouse cases look like generic black blobs, but the Aenllosi features a refined aesthetic with a slightly more tapered design and premium-feeling zippers. When I pull this out of my Peak Design backpack, it doesn’t look out of place next to high-end camera gear. The interior is lined with a super-soft, shock-absorbent material that feels like high-end microfiber. It protects the delicate MagSpeed scroll wheel from dust and lint, which is a major issue with the 3S over time. The fit is incredibly precise, and the external loop is reinforced, making it safer to clip to the outside of a bag if you run out of room. It’s slightly more expensive than the Khanka, but the build quality and tactile experience justify the jump for professionals.

co2CREA Hard Case View on Amazon
If you find the LTGEM a bit too bulky, the co2CREA Hard Case is a fantastic alternative. It has a slightly more “form-fitting” exterior that shaves off a few millimeters of height and width. This might not sound like much, but when you’re trying to zip up a saturated tech pouch, every millimeter counts. The case still uses EVA foam for the shell, so you aren’t sacrificing impact protection. One thing I’ve noticed is that the co2CREA tends to have a slightly stiffer zipper out of the box, which breaks in over time. It doesn’t have a dedicated “dongle slot” as defined as the LTGEM, but the mouse fits so securely that the receiver can usually be tucked in the mesh without rattling around. It’s a solid, reliable choice that sits right in the middle of the pack for quality and price.

Frequently Asked Questions
Will these cases fit the older MX Master 3?
Yes, they will. The external dimensions of the MX Master 3 and the MX Master 3S are identical. The differences between the two models are entirely internal (quieter clicks and an upgraded 8,000 DPI sensor). Any case labeled for the “MX Master 3” will fit your 3S perfectly, and vice versa. You don’t need to hunt for a 3S-specific model if you find a better deal on a version labeled for the older mouse.
Is a hard case really necessary for this mouse?
In my professional opinion, yes. The MX Master 3S uses a magnetic MagSpeed scroll wheel that is quite sophisticated. If the wheel is pressed at an odd angle for extended periods—like when it’s shoved into a tight backpack pocket—it can lead to scrolling inconsistencies or mechanical failure. A hard EVA case creates a “safe zone” for the wheel and ensures the mouse isn’t clicking and wasting battery while you travel.
Where should I store the USB receiver?
Most high-quality cases, like the LTGEM, have a dedicated molded slot specifically for the Logi Bolt or Unifying receiver. If your case only has a mesh pocket, I recommend putting the receiver in a small plastic baggie before placing it in the pocket. This prevents the metal connector of the USB receiver from rubbing against the side of your mouse and causing cosmetic scratches during bumpy flights or commutes.
Can these cases hold the charging cable too?
Most can, but it’s a tight squeeze. Cases like the Khanka and LTGEM feature a mesh pocket in the lid. You can usually fit the standard 3-foot USB-C cable that comes with the mouse. However, if you’re trying to fit a longer, thicker braided cable, you might find that the lid won’t close without putting pressure on the top of the mouse. For travel, I usually stick to the original, thinner cable.
Does the case protect against water spills?
While EVA foam itself is waterproof, these cases are “water-resistant” rather than “waterproof.” The main point of entry for liquid is the zipper track. Most of these cases use standard zippers rather than the sealed, weather-resistant zippers you see on high-end camera bags. They will survive a splash or a light rain, but you definitely shouldn’t submerge them or leave them in a puddle, as moisture will eventually seep through the teeth.
Final Verdict
For most users, the LTGEM Hard Case is the definitive choice; its molded interior ensures your MX Master 3S stays in pristine condition regardless of how messy your bag gets. If you are a digital nomad trying to save every penny, the Hermitshell offers basic security for a steal. Those who want a slightly more refined, professional look should opt for the Aenllosi. Regardless of your choice, getting your mouse out of your bag’s side-pocket and into a shell is a smart move.
