X-Small is the least commonly stocked size in industrial PPE — and that gap in supply is exactly where workplace injuries happen. Workers with smaller hands who are issued oversized gloves experience reduced grip strength, impaired dexterity, and increased likelihood of removing the glove for precision tasks. The MU3664K-XS closes that gap, delivering genuine goatskin leather palm construction and a Kevlar liner for flame resistance and cut protection in the smallest available size of the Mustang HiDex series.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eGenuine goatskin leather palm — premium, tight-grain, naturally supple protection\u003c\/li\u003e\n  \u003cli\u003eKevlar liner provides inherent flame resistance and ANSI-rated cut protection\u003c\/li\u003e\n  \u003cli\u003eDrivers glove construction — unlined back for flexibility and breathability\u003c\/li\u003e\n  \u003cli\u003eHiDex platform engineered for maximum dexterity within the protection category\u003c\/li\u003e\n  \u003cli\u003eANSI\/ISEA 105 cut resistance from Kevlar fiber construction\u003c\/li\u003e\n  \u003cli\u003eFR performance — Kevlar will not ignite, melt, or drip under flame exposure\u003c\/li\u003e\n  \u003cli\u003eKeystone and wing thumb placement for natural, comfortable hand positioning\u003c\/li\u003e\n  \u003cli\u003eSize: X-Small — smallest available size in the Mustang HiDex Kevlar FR line\u003c\/li\u003e\n  \u003cli\u003eAddresses the persistent PPE gap for workers with the smallest hand dimensions\u003c\/li\u003e\n  \u003cli\u003eMCR Safety SKU: MU3664K-XS\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eDetailed Description\u003c\/h2\u003e\n\u003cp\u003eX-Small is routinely absent from industrial PPE stockrooms, and this omission carries real safety consequences. When a worker with X-Small hands is given a Small or Medium glove, the excess material at the fingertips reduces tactile feedback and increases the chance the glove catches on machinery or equipment. In trades requiring FR-rated hand protection — welding, electrical, oil and gas, petrochemical — an ill-fitting glove is not merely uncomfortable. It can interfere with grip on valve handles, reduce the precision needed for torch operations, and create a snag hazard near rotating equipment. The MU3664K-XS eliminates these risks for the workers who need this size.\u003c\/p\u003e\n\n\u003cp\u003eThe construction of the MU3664K-XS mirrors the entire Mustang HiDex Kevlar FR series: a genuine goatskin leather palm that is the first line of defense against abrasion, cuts, and contact heat, and a Kevlar liner that adds the FR and cut-resistant properties that make this glove a multi-hazard solution. Goatskin leather is chosen specifically for its tight grain, which produces a thinner, more dexterous protective layer compared to cowhide split leather. In the X-Small size, where hand dimensions are already compact, the low-bulk character of goatskin is especially important — the resulting glove feels close to the hand and responsive rather than padded and imprecise.\u003c\/p\u003e\n\n\u003cp\u003eKevlar is not merely a marketing term in this context. DuPont's para-aramid fiber has an established performance record in protective textiles. Its key properties for this application are thermal stability (it does not melt or produce burning droplets), inherent flame resistance (it chars rather than burns), and high tensile strength relative to its weight (it resists cutting forces from sharp edges). In the MU3664K-XS, these properties translate to a glove that protects against the laceration hazards of sharp metal, glass, and sheet material, and the flash fire or torch flame hazards of welding and cutting environments.\u003c\/p\u003e\n\n\u003cp\u003eThe HiDex name reflects MCR Safety's design philosophy for this series: high dexterity is not a secondary consideration, it is a primary engineering objective. In a traditional fully lined safety glove, the back of the hand is encased in liner material that restricts bending at the knuckles and reduces the hand's natural range of motion. The drivers glove format used in the MU3664K-XS leaves the back unlined, preserving the hand's ability to cup, grip, and flex naturally. For X-Small hands already adapted to fine work — often the hands of workers who gravitate toward precision trades — this design choice makes the glove a tool rather than an obstacle.\u003c\/p\u003e\n\n\u003cp\u003eSafety managers responsible for inclusive PPE programs should note that the MU3664K-XS is not a specialty or niche product — it is the correct size for a real segment of your workforce. Whether that includes apprentice workers, women in trades, or simply employees who have always made do with ill-fitting gloves, stocking the XS size is a straightforward way to demonstrate that your hand protection program is built for the actual people doing the work.\u003c\/p\u003e\n\n\u003ch2\u003eApplications and Use Cases\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eWorkers with X-Small
