Why the MCR Safety MU3664K combines leather, cut, and flame protection
Some jobs need three things from one glove: the abrasion resistance and grip of real leather, cut protection, and flame resistance. The MU3664K delivers all three — a genuine goatskin leather palm for durable grip, a Kevlar liner that adds ANSI-rated cut protection and inherent flame resistance that will not ignite, melt, or drip, and a HiDex open-back build that keeps dexterity high. It is a drivers glove that does not force you to trade protection for feel. As leather work gloves go, this is the cut-and-FR leather pick, and the leather-glove guide and cut-glove guide cover how to match glove to task. It brings leather, cut, and flame together.
Safety first: the MU3664K is a leather cut and FR glove, not a chemical glove — it is not rated for a chemical splash hazard. For solvents or acids, wear dedicated chemical-resistant gloves selected by breakthrough time, and see the chemical-resistant gloves guide. The listing states Kevlar-based cut resistance but does not give a numeric cut level, so confirm the A-rating on the listing and use the ANSI A1-A9 cut-level guide. Its flame resistance is one part of an FR program, not a full arc-flash ensemble. Replace worn gloves.
What the MCR Safety MU3664K listing documents
From the published specs: a genuine goatskin leather palm; a Kevlar liner for flame resistance and ANSI-rated cut protection; a HiDex open-back drivers construction with keystone and wing thumb; and an X-Small-through-2X-Large size range. These are true goatskin leather gloves credentials and a genuine set of kevlar fr gloves — dexterous leather driver gloves. The Kevlar will not ignite, melt, or drip under flame, as listed.
How the MCR Safety MU3664K compares to other gloves
For a synthetic-leather hi-vis impact glove, the MCR Safety PD6901; for a needle-resistant duty glove, the PD4900; for a knit high-cut glove, the A7 Ergodyne ProFlex 7072 or A8 MCR 92743LT; and for the category, the mechanics cut-glove guide. The cut-vs-impact guide covers the trade-offs.
Choosing the right glove for the hazard
Match the glove to the dominant hazards and to any FR requirement. For coating and cut families, browse the cut-resistant gloves, mechanics gloves, and nitrile gloves collections; for heat, the heat-resistant gloves and welding gloves collections; for impact, the impact-resistant gloves collection and impact gloves guide; and for vibration, the anti-vibration gloves collection.
Where it fits by job and team orders
The MU3664K suits utility, oil-and-gas, and industrial crews who need leather grip with cut and flame protection, and who value stocking the full size range including hard-to-find X-Small. Confirm the cut level, keep a rated chemical glove for solvent tasks, follow your FR program for the full ensemble, and replace worn pairs promptly. For team orders, quantity purchasing runs through a free Amazon Business account — volume pricing, PO numbers at checkout, and tax-exempt eligibility for qualifying organizations, with the walkthrough linked in our footer.
Frequently asked questions
What is the MCR Safety MU3664K Mustang HiDex?
A driver-style glove with a genuine goatskin leather palm and a Kevlar liner that provides inherent flame resistance and ANSI-rated cut protection. The HiDex open-back build maximizes dexterity within the protection category.
What does the Kevlar liner do?
The Kevlar liner delivers inherent flame resistance - it will not ignite, melt, or drip under flame exposure - and provides ANSI/ISEA 105 cut resistance from the aramid fiber construction.
What cut level is it?
The listing states ANSI/ISEA 105 cut resistance from the Kevlar construction but does not specify a numeric cut level. Confirm the exact A-rating on the product listing before selecting it for a defined cut hazard.
Why goatskin leather?
Goatskin is a premium, tight-grain, naturally supple leather that delivers abrasion resistance and grip while staying flexible, which suits the drivers-glove design for equipment operation.
Are these chemical-resistant gloves?
No - the MU3664K is a leather cut and FR glove and is not rated for a chemical splash hazard. For solvents or acids, use dedicated chemical-resistant gloves selected by breakthrough time for the chemical.
What is the HiDex open-back design?
An unlined, open-back construction that reduces bulk and heat on the back of the hand and improves knuckle flexibility and breathability for extended wear.
What sizes are available?
This listing covers the Mustang HiDex Kevlar FR line from X-Small through 2X-Large. X-Small is highlighted because it is the least-commonly-stocked size and a proper fit is essential for grip and dexterity.
Why does X-Small matter?
Workers with smaller hands issued oversized gloves lose grip strength and dexterity and are more likely to remove the glove for precision tasks. Stocking X-Small closes a real PPE gap.
Does the FR rating replace a full FR program?
No - the Kevlar provides flame-resistant hand protection, but it is one part of an FR program. Follow your facility's FR and arc-flash requirements for the full ensemble.
Does it stop punctures?
Cut resistance and puncture resistance are different ratings. The Kevlar cut protection covers slicing cut forces, not punctures; choose a puncture-rated glove for those hazards.
When should I replace them?
Replace the gloves when the leather cracks or wears through, the Kevlar liner shows damage, or fit and grip degrade - worn gloves no longer deliver their protection.
How do I order for a team?
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.
