The MCR Safety MU3664K Mustang HiDex Goatskin Kevlar FR Gloves is a cut-resistant gloves from MCR Safety, stocked at $46.79. This review restates what the product page documents, places it in its hand protection lane, and points to the ranked guides for the head-to-head field.
What the Product Page Documents
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.

What are the alternatives to the MCR Safety MU3664K Mustang HiDex Goatskin Kevlar FR Gloves?
The sibling cut-resistant gloves options linked in this review, ranked head-to-head in the hand protection guides below — start with the buyer's guides for the field view.
What do ANSI cut levels A1-A9 mean?
Grams of force a blade needs to cut through in standardized testing — A1 (200g) through A9 (6,000g+). Match the level to the hazard: A2-A4 covers general handling, A5+ for glass, sheet metal, and blades. The level on the listing is the level.
What does ANSI/ISEA 138 cover?
Back-of-hand impact protection, levels 1-3 — the standard behind rated impact gloves. TPR padding without a stated 138 level is comfort-tier protection; the reviews here keep that distinction explicit.
What does glove mil thickness mean?
One mil = 0.001 inch of film thickness on disposables. Thicker resists tears and lasts longer; thinner gives feel. Exam-grade 3-5 mil for light tasks, 6-8+ mil for shop duty — polymer choice still matters more than thickness.
Nitrile, latex, or vinyl — which disposable?
Nitrile for chemical splash and punctures (and latex allergies), latex for elasticity and feel where allergies permit, vinyl for cost-sensitive light tasks. The complete guide linked below runs the decision in full.
How do I size work gloves correctly?
Measure palm circumference and match the maker's chart — patterns differ across brands. Coated and cut-resistant knits should fit snug; a loose cut glove wrinkles and snags exactly where the blade lands.
When do coated work gloves get replaced?
When the coating wears through at fingertips or palm, when knit runs appear, or when embedded grime stiffens the shell. Coating breach on a cut-rated glove ends the rating where it matters most.
Can cut-resistant gloves be washed?
Most knit cut gloves take machine washing per their listing's care line — it extends life materially. Disposables never; coated gloves depend on the coating chemistry. Check the listed care instructions.
Are cut-resistant gloves puncture-proof?
No — cut resistance measures blade slicing, not needle puncture; hypodermic protection is a separate rating few gloves carry. Sharps handling needs gloves rated for the actual mechanism.
Do food tasks need special gloves?
Food-contact-safe marking on the listing is the gate — several cut-resistant and nitrile lines carry it for food processing. A shop glove without the marking stays out of the kitchen.
What does OSHA require for hand protection?
29 CFR 1910.138: gloves matched to the assessed hazard — cut, chemical, thermal, or general mechanical. The assessment picks the rating class; the listing's stated levels tell you whether a glove satisfies it.
Why do gloves come in dozens on some listings?
Consumable economics — coated and disposable gloves are bought by the dozen or case because替 rotation and replacement are the model. Per-pair math on the case price is the honest comparison.
Touchscreen compatibility — real or marketing?
Real where listed — conductive fingertip yarns work. The tradeoff is usually a thinner tip, which matters on cut-rated gloves; the listing states both or neither.
The Bottom Line
Rated 4.6/5 on documented spec, configuration, and value. The MCR Safety MU3664K Mustang HiDex Goatskin Kevlar FR Gloves does the job its listing describes — the guides above tell you whether it's the right pick against the field.

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.
