What the Product Page Documents
Published · Last updated
The MCR Safety MU3664K-XXXL Mustang HiDex Goatskin Kevlar FR Gloves in XXX-Large provide utility-grade hand protection in the largest standard glove size in the Mustang HiDex series. Built with a genuine goatskin leather palm and a Kevlar liner, SKU MU3664K-XXXL delivers natural leather dexterity, inherent cut resistance from the aramid fiber construction, and the flame-resistant characteristics of Kevlar — making these gloves appropriate for utility line work, welding-adjacent tasks, electrical maintenance, and general industrial applications where FR protection is a program requirement. The drivers-style cut maximizes palm dexterity and wrist mobility, while the XXX-Large size addresses a segment of the workforce with larger hands that standard industrial glove programs frequently underserve.
Goatskin leather has a well-established reputation in the PPE industry as the premium natural leather material for gloves requiring both dexterity and durability. Compared to cowhide, goatskin is lighter, thinner, and more conformable, and its natural lanolin content provides a degree of inherent moisture resistance. For utility linemen, electricians, and maintenance workers who need to manipulate wires, cables, and components while wearing gloves, goatskin's ability to transmit tactile feedback through the palm is a practical performance advantage. The MU3664K-XXXL uses genuine goatskin — not split leather or synthetic alternatives — ensuring workers in the XXX-Large size range have access to the same premium material as those in smaller standard sizes.
The Kevlar liner underlying the goatskin palm provides two distinct performance benefits. The first is cut resistance: Kevlar (DuPont's registered trademark for para-aramid fiber) has a high tensile strength relative to its weight, and woven Kevlar fabric resists cutting and tearing forces effectively as a glove liner. The second is flame resistance: Kevlar is an inherently FR fiber, meaning its flame-resistant properties are a chemical characteristic of the polymer chain structure, not a topical treatment that can wash out or wear away. For utility line workers and welding-adjacent tasks — environments where an arc flash or weld spatter event can cause brief but intense thermal exposure to the hands — a Kevlar-lined glove provides meaningful incremental protection over non-FR alternatives.
Where It Earns Its Slot
Where it earns its slot: The MCR Safety MU3664K-XXXL Mustang HiDex Goatskin Kevlar FR Gloves in XXX-Large provide utility-grade hand protection in the largest standard glove size in the Mustang HiDex series. Built with a genuine goatskin leather. Everything below measures the product against that role: its honest limits, its true alternatives, and where the linked guides rank it.
Honest Limits
Its boundaries are the category's: protection is limited to the rated hazards at the rated levels, chemical exposure is governed by breakthrough time rather than resistance in the abstract, and fit determines whether any of it reaches the hand. Verify the marking against the task before relying on it.

About the Author
Steven Eaton is the founder of WC Safety and an industrial PPE specialist who sources and evaluates hand protection equipment for industrial and construction buyers.
How We Review
Hand-protection reviews restate ANSI/ISEA 105 cut levels, ANSI/ISEA 138 impact levels, and mil thicknesses exactly as each listing states them — never inferred from appearance or price. Where a listing claims no level, the review says so and treats the glove as unrated for that hazard. Ratings reflect documented spec, configuration, and value — the basis is stated, not invented testing.

Editorial Standards
Claims are drawn from listing data and published standards. WC Safety does not invent specifications or test results. Report errors to safetynw2012@gmail.com.
Primary sources for this page
The wording behind this page sits in OSHA 29 CFR 1910.138, OSHA 29 CFR 1910.132, NIOSH Personal Protective Equipment.
Why trust this page?
Why trust this page? Every figure on it is taken from the published text of the standard or the manufacturer document named beside it, not from a secondary summary. WC Safety is an independent PPE review site: we hold no inventory and sell nothing directly, so there is no product we need this page to favour. Where sources disagree, the page says so and plans on the more conservative figure rather than picking one.
Methodology: how this page is maintained
Methodology. Figures are read from the primary source and re-checked whenever the underlying standard or a manufacturer document changes. No laboratory testing is performed for this page. Where a figure is not published, the page states that rather than estimating it, because a plausible invented number is more dangerous than an absent one.
