Kevlar
Para-aramid synthetic fiber with extraordinary strength-to-weight ratio. Used in protective clothing, aerospace, and military applications.
Material Score Breakdown
7-axis material rubric, not a garment verdict — see disclosure below.
How long the fabric lasts with regular use
Softness, feel against skin, wearability
Air flow and ventilation
Heat retention and insulation
Ability to pull sweat away from skin
Environmental impact of production and disposal
How easy it is to wash, dry, and maintain

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
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.
+26 vs Kevlar · 76/100
Membrane technology that is waterproof yet breathable. A laminate applied to other fabrics rather than a fabric itself.
+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.
+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.
Care Guide
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
