What the Product Page Documents
Published · Last updated
The MCR Safety MU3664K-XS Mustang HiDex Goatskin Kevlar FR Gloves — X-Small (SKU: MU3664K-XS) represent a critical inclusion in any comprehensive FR hand protection program. 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.
X-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.
The 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.
Where It Earns Its Slot

Honest Limits
Honest limits: glove ratings are per-hazard, not general toughness. Cut, puncture, abrasion, chemical, and thermal performance are separate tests, and this glove protects only on the axes its marking actually covers. Inspect for breaches and retire on damage — degraded gloves protect on paper only.

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.

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.
