Sock Material Standards
We at SIA are sticklers for quality:
- Cotton: 80% or higher thread count, or 100% cotton for those who insist on being old-fashioned
- Spandex: 5% or higher elastane content for that extra stretch
- Coolmax: 100% breathable, moisture-wicking, and smell-repelling fabric
Don't even get us started on our rigorous standards for Sock Elasticity (SEC), Sock Durability (SD), and Sock Aesthetics (SA)...
