What this score doesn't measure

This is a material rating, not a verdict on any specific garment made from kevlar. The axes above are research-backed averages for the fiber itself.

×Construction. Yarn staple length, weave / knit structure, stitch count, finishing. Identical fiber, very different garments.
×Fabric weight (GSM). A 140 GSM tee and a 220 GSM tee made of the same kevlar feel and last very differently.
×Dye + finishing chemicals. Beyond the three we flag (PFAS, formaldehyde, antimony), dozens of textile finishes aren't modelled.

Best Uses

outerwear

Protective gear only, not for fashion

Pros

✓ Incredibly strong
✓ Cut and abrasion resistant
✓ Heat resistant
✓ Lightweight for its strength

Cons

✗ Very expensive
✗ Stiff and uncomfortable
✗ Degrades in UV light
✗ Not for everyday wear

Better alternatives

Higher-scored synthetic materials. Same category — what to consider instead.

Gore-TexB

+26 vs Kevlar · 76/100

Membrane technology that is waterproof yet breathable. A laminate applied to other fabrics rather than a fabric itself.

DyneemaB

+25 vs Kevlar · 75/100

Ultra-high-molecular-weight polyethylene (UHMWPE) fiber — the world's strongest fiber by weight. 15x stronger than steel, used in cut-resistant gear, ultralight backpacks, and high-performance sails.

HardshellB

+24 vs Kevlar · 74/100

Waterproof breathable membrane fabric (Gore-Tex, eVent, or similar technology) laminated to a face fabric. The gold standard for rain and storm protection in technical outerwear.

Special Notes

• Avoid prolonged UV exposure

• Do not bleach — degrades aramid fibers

• Follow manufacturer instructions — varies by product

Additional Care Tips

• Follow manufacturer care guidelines strictly — Kevlar is a specialized protective material
• Store away from UV light (sunlight, fluorescent) which degrades aramid fibers over time
• Do not bleach or use harsh chemicals — they weaken the fiber's protective properties
• Professional cleaning recommended; hand wash cold with mild detergent if manufacturer permits
• Air dry only — never tumble dry or iron; heat compromises the structural integrity
• Inspect regularly for damage — cut or abraded Kevlar loses its protective value
