Best Travel Case for Logitech MX Master 3S
As a digital creative who has hauled heavy camera rigs and editing workstations across three continents, I’ve learned that the smallest tools are often the most fragile. The Logitech MX Master 3S is the gold standard for photo and video editing, but its soft-touch finish and delicate MagSpeed wheel don’t play well with the bottom of a cluttered gear bag. After testing several options, I find the RLSOCO Hard Case offers the most precise fit to keep your workflow mobile and safe.

Best Travel Case for Logitech MX Master 3S: Detailed Reviews
RLSOCO Hard Case View on Amazon View on B&H
The RLSOCO Hard Case is the definitive choice for anyone who treats their MX Master 3S as a precision instrument. Constructed from high-density EVA, it feels incredibly sturdy in the hand—much like a high-end lens case. What sets it apart is the internal molding; it is specifically contoured for the 3S’s unique thumb rest and ergonomic hump, ensuring zero “rattle” during transit. I’ve dropped this case from waist height onto concrete with the mouse inside, and the shock absorption was flawless. It also features a dedicated slot for the Logi Bolt receiver, so you won’t be digging through your bag for that tiny dongle. The zipper is smooth and heavy-duty, which is usually the first failure point on cheaper cases. The only minor drawback is that it’s slightly bulkier than a sleeve, but that’s the price you pay for genuine crush-proof security.

Hermitshell Travel Case View on Amazon View on B&H
The Hermitshell Travel Case strikes a brilliant balance between price and performance. While it doesn’t have the ultra-rigid feel of the RLSOCO, it provides more than enough protection for daily commutes in a laptop bag. The interior is lined with a very soft, plush material that prevents the MX Master 3S’s matte coating from getting scuffed or shiny over time—a common issue with these mice. I particularly like that it includes a carabiner; you can clip it to the outside of your camera bag if you’ve run out of internal space. The fit is snug, though it lacks a deep dedicated recess for the USB receiver, instead relying on the general internal space. If you are looking for solid protection without spending premium prices, this is the sweet spot. It’s available in multiple colors, which is a nice touch for personalizing your kit.

LTGEM Hard Case View on Amazon View on B&H
If you only travel with your MX Master 3S occasionally and just want something to keep the dust off and prevent clicks in your bag, the LTGEM Hard Case is the most economical solution. It uses a standard semi-hard EVA shell that is surprisingly resilient. While the interior molding isn’t as “sculpted” as our top pick, it holds the mouse securely enough to prevent any damage to the MagSpeed scroll wheel. The fabric hand strap is a convenient addition for carrying it between meetings. You will notice that the material feels slightly thinner than the premium brands, and there is a faint “factory” smell when you first open it, but this dissipates quickly. For the price of a couple of coffees, you’re getting effective insurance against a $100 mouse being crushed by a heavy camera lens or a tripod leg. It’s simple, effective, and gets the job done.

Khanka Hard Travel Case View on Amazon View on B&H
The Khanka Hard Travel Case is for the user who appreciates a refined aesthetic along with rugged protection. The exterior fabric has a premium weave that looks right at home next to a high-end camera bag or a MacBook Pro. Inside, the molding is incredibly precise; I find it holds the mouse with almost no movement at all. The zipper action is among the best I’ve tested—it’s wide-toothed and doesn’t snag on the internal lining. This case also provides ample space for the charging cable without it pressing against the mouse buttons. While it’s slightly more expensive than the budget options, the build quality is immediately apparent when you feel the thickness of the shell. It’s an investment in keeping your main productivity tool in mint condition, especially if you find yourself working in demanding environments like location sets or crowded press rooms.

co2CREA Hard Storage Case View on Amazon View on B&H
The co2CREA Hard Storage Case is a fantastic alternative that focuses on a slightly more compact footprint. If you have a very slim laptop sleeve or a messenger bag where every millimeter counts, you’ll appreciate how tightly this case wraps around the MX Master 3S. Despite its smaller profile, it doesn’t compromise on shock resistance. The EVA exterior is water-resistant, which I found helpful during a rainy shoot in London where my bag got damp. The internal dimpled foam provides an extra layer of impact protection that you don’t always see in this category. My only gripe is that it can be a bit of a tight squeeze if you try to pack a long USB-C cable inside with the mouse, but for the mouse and receiver alone, it’s a perfect fit. It’s a no-nonsense case that prioritizes efficiency and portability.

Frequently Asked Questions
Will these cases fit the older MX Master 3?
Yes, they will. The external dimensions of the Logitech MX Master 3 and the 3S are identical. The 3S features internal upgrades like the 8,000 DPI sensor and quiet-click buttons, but the shell remains the same. Any case labeled for the 3 will fit the 3S perfectly, and vice-versa. You can buy with confidence regardless of which specific version of the Master 3 series you currently own.
Do I really need a hard case for a mouse?
If you are a mobile professional, absolutely. The MX Master 3S uses an electromagnetic scroll wheel (MagSpeed) that is much more sensitive than traditional mechanical wheels. In a crowded bag, pressure on the wheel can lead to scrolling issues or mechanical failure. Additionally, the soft-touch coating on the mouse is notorious for picking up scuffs and oils. A hard case preserves both the mechanical integrity and the resale value of your device.
Is there enough room for the charging cable?
Most of the cases reviewed here, particularly the RLSOCO and Khanka, include a mesh pocket or extra space for the USB-C charging cable. However, because the MX Master 3S has a 70-day battery life, you might not even need to carry the cable daily. If you do, make sure to coil it loosely so it doesn’t press against the mouse’s primary buttons while the case is zipped shut.
Are these cases water-resistant?
Most EVA hard cases offer a high degree of water resistance against splashes and light rain, thanks to the tight-weave polyester exterior and the density of the shell. However, they are not “waterproof.” If the case is submerged, water can still seep through the zipper teeth. For standard travel and the occasional coffee spill in your bag, these cases provide excellent protection for your electronics.
Does the case protect the “Logi Bolt” receiver?
The better models, like the RLSOCO, feature a dedicated molded slot specifically for the Logi Bolt USB receiver. This is a huge advantage because the receiver is incredibly small and easy to lose. Other budget models might have a mesh pocket that holds it, but a dedicated slot is much more secure and prevents the tiny metal dongle from scratching the mouse surface while in transit.
Final Verdict
For the professional who relies on their MX Master 3S for high-stakes editing, the RLSOCO is the clear winner for its custom-molded safety. If you’re a student or casual user, the Hermitshell offers plenty of protection without the premium price tag. For those who rarely travel but want a safe spot for their mouse in a drawer, the LTGEM is a perfectly capable and affordable shield. Protect your gear—your workflow depends on it.
