Detailed Use Case Scores
Higher-scored synthetic materials. Same category — what to consider instead.
+6 vs PrimaLoft · 76/100
Membrane technology that is waterproof yet breathable. A laminate applied to other fabrics rather than a fabric itself.
+5 vs PrimaLoft · 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.
+4 vs PrimaLoft · 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.
