Built from full-grain goatskin leather with a Kevlar aramid fiber lining and waterproof extended gauntlet cuff, the MU3664KGW-S is NFPA 2112 compliant and designed for the full range of welding, utilities, oil and gas, and petrochemical applications where thermal and cut hazards intersect. As more women enter skilled trade industries and FR PPE requirements expand across sectors, proper Small sizing in premium gauntlet gloves is no longer optional — it is a workplace equity and compliance requirement.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eFull-grain goatskin leather shell — naturally dexterous, fine-grained, and break-in ready\u003c\/li\u003e\n  \u003cli\u003eKevlar aramid fiber lining for FR performance and supplementary cut resistance\u003c\/li\u003e\n  \u003cli\u003eNFPA 2112 flame-resistant rating for flash fire protection\u003c\/li\u003e\n  \u003cli\u003eExtended waterproof gauntlet cuff — prevents wrist-gap exposure from spatter and splash\u003c\/li\u003e\n  \u003cli\u003eHiDex pre-curved ergonomic pattern — optimized for precision grip and reduced hand fatigue\u003c\/li\u003e\n  \u003cli\u003eANSI\/ISEA 105 cut resistance certification\u003c\/li\u003e\n  \u003cli\u003eSmall sizing — appropriately fit for smaller-handed workers without compromising protection\u003c\/li\u003e\n  \u003cli\u003eReinforced thumb crotch and fingertips for extended wear life\u003c\/li\u003e\n  \u003cli\u003eCompliant with OSHA 29 CFR 1910.138 and relevant NFPA 70E programs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eDetailed Description\u003c\/h2\u003e\n\u003cp\u003eThe availability of a Small size in a premium FR gauntlet series like the MCR Safety Mustang HiDex is significant for two converging reasons. First, the skilled trades workforce has been diversifying rapidly, with women now representing a growing percentage of welders, pipefitters, ironworkers, electricians, and oil and gas field workers. Women in these industries have long encountered a PPE market that was built around a male default — with \"Small\" often meaning a glove designed for a medium male hand that was merely labeled smaller. Ill-fitting gloves are not just uncomfortable; they are a safety hazard. A glove with excess material at the fingertips reduces tactile sensitivity, can catch on equipment, and may encourage workers to remove PPE to perform fine tasks. The MU3664KGW-S is designed to fit small hands correctly, delivering the same protection and dexterity profile as the Medium and Large versions without the bulk that plagues many \"one-size-down\" industrial gloves.\u003c\/p\u003e\n\n\u003cp\u003eSecond, flame-resistant handwear requirements have expanded significantly in recent years. OSHA's enforcement of 29 CFR 1910.269 for electric power generation and distribution has driven broader adoption of FR PPE across utility workforces. NFPA 2112 and NFPA 70E continue to set expectations in petrochemical and electrical industries. As these requirements reach deeper into the workforce — including newer workers, apprentices, and cross-trained employees — the need for correctly sized FR gloves across all size ranges becomes a compliance management priority, not just a comfort issue. An employer who stocks only Medium and Large gloves is not in compliance for workers who require a Small.\u003c\/p\u003e\n\n\u003cp\u003eThe goatskin leather shell of the MU3664KGW-S contributes both to comfort and protection. Goatskin's tight grain structure means that even in a Small size, the leather lays flat against the hand without the wrinkling or bunching that can occur with coarser leather in smaller cuts. The result is a glove that maintains full dexterity even for workers managing fine-pitch valves, instrument panels, or wiring terminations. Combined with the pre-curved HiDex finger pattern, the Small size of the Mustang Gauntlet delivers a fit that makes it genuinely wearable for extended periods — a prerequisite for consistent PPE compliance on the job site.\u003c\/p\u003e\n\n\u003cp\u003eThe Kevlar aramid lining provides the FR backbone of the protective system. Para-aramid fibers are inherently flame resistant and do not undergo the melt-and-drip failure mode of synthetic materials such as polyester or nylon. When a flash fire or arc flash event occurs, the Kevlar lining forms a stable barrier that slows heat transfer to the skin while the leather shell chars and resists penetration. This system-level protection is what NFPA 2112 tests and certifies, and it functions identically whether the glove is a Small or an Extra-Large. Size does not diminish the protective performance of the MU3664KGW-S.\u003c\/p\u003e\n\n\u003cp\u003eThe waterproof extended gauntlet cuff is particularly important for smaller-framed workers, whose forearm dimensions may mean that standard gauntlet cuffs fit loosely and allow more intrusion at the wrist gap. MCR Safety's construction of the MU3664KGW-S accounts for the proportional differences in Small sizing to ensure the cuff seals appropriately without being so tight as to restrict circulation. For women and smaller-statured men working in environments with wrist-gap hazards — overhead welding, hot work in confined spaces, pressurized steam systems — this fit precision is a direct contribution to injury prevention.\u003c\/p\u003e\n\n\u003ch2\u003eApplications and Use Cases\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eWelding operations across trade industries — MIG, TIG, and stick — for workers requiring Small sizing\u003c\/li\u003e\n  \u003cli\u003eWomen in skilled trades requiring properly fitted FR gauntlet gloves for compliance\u003c\/li\u003e\n  \u003cli\u003eApprentice and entry-level workers entering FR-regulated industries for the first time\u003c\/li\u003e\n  \u003cli\u003eElectrical utility operations under NFPA 70E arc flash PPE requirements\u003c\/li\u003e\n  \u003cli\u003eOil and gas field operations — completions, production, and maintenance roles\u003c\/li\u003e\n  \u003cli\u003ePetrochemical and refinery maintenance where flash fire risk requires FR handwear\u003c\/li\u003e\n  \u003cli\u003eStructural steel and ironwork for workers with smaller hand profiles\u003c\/li\u003e\n  \u003cli\u003eIndustrial boiler and furnace maintenance\u003c\/li\u003e\n  \u003cli\u003ePipeline construction and maintenance in variable weather and wet conditions\u003c\/li\u003e\n  \u003cli\u003eFacilities management in manufacturing plants with concurrent thermal and cut hazards\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eAttribute\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSKU \/ Model\u003c\/td\u003e\n\u003ctd\u003eMU3664KGW-S\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003eSmall\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePalm Material\u003c\/td\u003e\n\u003ctd\u003eFull-grain goatskin leather\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLining\u003c\/td\u003e\n\u003ctd\u003eKevlar aramid fiber\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCuff Style\u003c\/td\u003e\n\u003ctd\u003eExtended gauntlet, waterproof\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFlame Resistance\u003c\/td\u003e\n\u003ctd\u003eYes — FR rated, NFPA 2112 compliant\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCut Resistance\u003c\/td\u003e\n\u003ctd\u003eANSI\/ISEA 105 rated\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWaterproof\u003c\/td\u003e\n\u003ctd\u003eYes (cuff and moisture barrier)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDexterity Rating\u003c\/td\u003e\n\u003ctd\u003eHigh (HiDex series)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePrimary Standards\u003c\/td\u003e\n\u003ctd\u003eNFPA 2112, ANSI\/ISEA 105, OSHA 1910.138\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSold As\u003c\/td\u003e\n\u003ctd\u003ePer pair\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eMCR Safety\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eMustang HiDex (MU3664KGW)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eRelated Products\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/cut-resistant-gloves\"\u003eCut-Resistant Gloves — Full Collection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/wcsafety.com\/collections\/hand-protection\"\u003eWork Gloves — All Categories\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/wcsafety.com\/collections\/hand-protection\"\u003eMCR Safety Products at WC Safety\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/wcsafety.com\/collections\/hand-protection\"\u003eFlame-Resistant Work Gloves\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/wcsafety.com\/collections\/hand-protection\"\u003eWelding Gloves\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/wcsafety.com\/collections\/hand-protection\"\u003eWork Gloves for Women in Trade Industries\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdl\u003e\n  \u003cdt\u003eWhy is it important to have a properly sized Small FR gauntlet glove?\u003c\/dt\u003e\n  \u003cdd\u003eA glove that is too large reduces tactile sensitivity, creates excess material that can catch on equipment, and may cause workers to remove their PPE for fine tasks — negating the protective benefit entirely. Proper fit is a safety requirement, not a comfort preference. As women and smaller-statured workers increasingly populate FR-regulated industries, correctly sized Small gloves are a compliance necessity.\u003c\/dd\u003e\n\n  \u003cdt\u003eAre MCR Safety's FR gloves appropriate for women in welding and oil and gas roles?\u003c\/dt\u003e\n  \u003cdd\u003eYes. The MU3664KGW-S in Small sizing is specifically relevant for women working in welding, oil and gas, electrical utilities, and other FR-regulated industries. The same NFPA 2112 protection level is delivered in a properly fitted Small, without the bulk and ill-fit that characterize many industrial gloves when worn by workers with smaller hands. WC Safety encourages employers to stock the full size range of their FR gloves to ensure compliant PPE for every member of their workforce.\u003c\/dd\u003e\n\n  \u003cdt\u003eWhat FR standards does the MU3664KGW-S comply with?\u003c\/dt\u003e\n  \u003cdd\u003eThe MU3664KGW-S is compliant with NFPA 2112, the Standard on Flame-Resistant Clothing for Protection of Industrial Personnel Against Short-Duration Thermal Exposures from Fire. It is also relevant to NFPA 70E arc flash PPE requirements and meets OSHA 29 CFR 1910.138 hand protection standards.\u003c\/dd\u003e\n\n  \u003cdt\u003eHow do I measure for a Small glove?\u003c\/dt\u003e\n  \u003cdd\u003eUse a flexible tape measure to measure the circumference of the dominant hand at the widest part of the palm, excluding the thumb. A measurement of approximately 7 to 7.5 inches typically corresponds to a Small in MCR Safety's sizing. Refer to MCR Safety's sizing documentation for confirmation, or contact WC Safety for sizing assistance.\u003c\/dd\u003e\n\n  \u003cdt\u003eDoes the Small size of the Mustang HiDex provide the same protection level as Medium or Large?\u003c\/dt\u003e\n  \u003cdd\u003eYes. The protective performance of the MU3664KGW-S — FR rating, cut resistance, waterproof cuff, and Kevlar lining — is identical to the Medium (MU3664KGW-M) and Large (MU3664KGW-L). Size affects fit, not protection level. All sizes in the Mustang HiDex series meet the same NFPA 2112 and ANSI\/ISEA 105 certifications.\u003c\/dd\u003e\n\n  \u003cdt\u003eCan apprentices and newer workers use this glove for their first FR assignments?\u003c\/dt\u003e\n  \u003cdd\u003eAbsolutely. The Mustang HiDex series is appropriate for any worker in an FR-regulated environment, regardless of experience level. For newer workers, the goatskin leather's immediate comfort and the HiDex dexterity-forward design can help with PPE acceptance — a common challenge when workers are adjusting to wearing protective gloves for extended periods.\u003c\/dd\u003e\n\n  \u003cdt\u003eWhat is the gauntlet cuff length on the MU3664KGW-S?\u003c\/dt\u003e\n  \u003cdd\u003eMCR Safety's Mustang HiDex gauntlet cuff is designed to extend several inches above the wrist to close the sleeve gap. For precise cuff measurements, refer to MCR Safety's product documentation or contact WC Safety. The cuff is proportionally fitted for Small sizing to ensure proper seal without excessive bulk.\u003c\/dd\u003e\n\n  \u003cdt\u003eDoes WC Safety offer bulk purchasing for the MU3664KGW-S for employer accounts?\u003c\/dt\u003e\n  \u003cdd\u003eYes. WC Safety is a B2B safety equipment distributor and supports bulk and fleet purchasing for employers. We recommend that employers stocking FR gloves carry the full size range — Small through Large — to ensure every employee has a properly fitted glove.
