Car covers range from a single PEVA sheet to 7-layer composites. The 3-4x price difference is almost always worth it.
Each layer serves a purpose: outer shell for UV reflection and waterproofing, waterproof membrane for water block, breathable middle for vapor escape, cushion layer for impact protection, soft inner fleece for paint protection.
Single-layer covers fail at extremes: too waterproof means condensation, too breathable means leaks. Single-layer PEVA degrades in 6-8 months of sun.
Real-world lifespan: Single PEVA 6-8 months. 2-3 layer 12-18 months. 4-Layer Oxford 24-36 months. 5-7 Layer Composite 36+ months.
Cost: A $25 single-layer cover replaced twice costs $50/year. A $60 multi-layer lasting 3 years costs $20/year. Multi-layer is cheaper long-term.
