Why the MCR Safety MU3664KGW covers heat, flame, and cut
Field trades like welding, line work, and oil and gas rarely face one hazard at a time — heat, flame, spatter, and sharp edges all show up together, and a plain leather driver glove is not enough. The Mustang HiDex answers with a layered build: full-grain goatskin for dexterity and heat resistance, a flame-resistant Kevlar liner for cut and thermal protection, and a waterproof extended gauntlet cuff for wrist and forearm coverage — listed NFPA 2112 compliant. Offering it in Small also closes a real gap for smaller-handed workers who are often left out of premium FR sizing. As welding gloves go, this is the FR gauntlet pick, and the best welding gloves guide and leather glove guide cover matching hide and lining to the job.
Safety first: the MU3664KGW is a flame-resistant, cut-lined leather gauntlet — its Kevlar liner adds cut and heat performance, but Kevlar here is a cut-and-thermal fiber, not a chemical rating, so it is not rated against a chemical splash hazard. And it protects your hands and forearms, not your eyes: arc-eye protection for welding requires a helmet with the correct shade, covered in the welding helmets guide, plus safety glasses. Confirm NFPA 2112 suits your program and pair it with proper eye and face protection.
What the MCR Safety MU3664KGW listing documents
From the published specs: full-grain goatskin leather; a flame-resistant Kevlar aramid liner; a waterproof extended gauntlet cuff; NFPA 2112 compliance as listed; a Small fit within a Small-to-XX-Large range. These are true fr welding gloves and genuine goatskin gauntlet gloves — durable kevlar lined gloves for field trades.
How the MU3664KGW compares to other gloves
For the largest fit of the same gauntlet, the MU3664KGW XXX-Large. Among welding gloves, compare the cowhide Tillman 50 gauntlet and Black Stallion cowhide, insulated Caiman deerskin, the traditional Lincoln K2979, the extra-long Rapicca 16-inch, and TIG-feel Lincoln K2981. For dedicated cut knits, the A5 MCR 92752 and A6 Ergodyne ProFlex 7061. The cut-resistant gloves guide and ANSI cut levels guide cover cut ratings.
Choosing the right glove for your hazard
Match the glove to the mix of hazards. For non-FR leather work, the leather work gloves collection; for chemical exposure, a dedicated chemical glove instead; and the full hand protection collection spans FR, cut, chemical, and impact options for building a complete kit.

Frequently asked questions
What is the MCR Safety MU3664KGW Mustang HiDex?
A flame-resistant leather gauntlet - full-grain goatskin over a Kevlar aramid liner with a waterproof extended gauntlet cuff, listed NFPA 2112 compliant. It is built for welding, utilities, oil and gas, and petrochemical work where thermal and cut hazards intersect, offered here in a Small fit.
Is it flame-resistant?
Yes - the listing states the Mustang HiDex gauntlet is NFPA 2112 compliant, and it uses a flame-resistant Kevlar liner under goatskin leather. NFPA 2112 is a standard for flame-resistant protective materials in industrial settings.
What does the Kevlar liner do?
The Kevlar aramid liner adds cut resistance and heat protection under the goatskin shell. Note that Kevlar here provides cut and thermal performance - it is not a chemical rating.
Why goatskin leather?
Full-grain goatskin is supple and naturally thermally resistant, giving dexterity for field tasks while contributing to the glove's heat protection. It pairs with the Kevlar liner and waterproof cuff for a durable FR gauntlet.
What is the waterproof gauntlet cuff for?
The extended gauntlet cuff covers the wrist and lower forearm against heat, spatter, and abrasion, and the waterproof construction helps in wet field conditions where a standard driver glove leaves gaps.
Why a Small size?
Premium FR gauntlets are often only stocked in larger sizes, leaving smaller-handed workers without a properly fitting option. This Small closes that gap so every worker gets certified FR protection that fits.
Is it a chemical glove?
No - it is a flame-resistant, cut-lined leather gauntlet. It is not rated against chemicals; for chemical hazards use a dedicated chemical-resistant glove.
What work is it for?
Welding, electric utilities and line work, oil and gas, and petrochemical operations where heat, flame, and cut hazards occur together and a plain leather driver glove is not enough.
What sizes does it come in?
This listing covers Small through XX-Large (MU3664KGW-S up to MU3664KGW-XXL); an XXX-Large is offered separately. Size to a firm, comfortable fit so the cuff seals and the liner works.
Is it arc-eye protection?
No - it protects the hands and forearms. Eye and face protection for welding requires a welding helmet with the correct shade; the gauntlet protects your hands, not your eyes.
How do I care for it?
Keep it dry when possible and let it dry fully after wet work; store it away from direct heat and sunlight. Retire it once the leather cracks or burns through, the liner is compromised, or seams fail.
How do I order for a crew?
Quantity purchasing runs through a free Amazon Business account - volume pricing, PO numbers at checkout, and tax-exempt eligibility for qualifying organizations. The bulk-ordering walkthrough is linked in our site footer.
