- Durability: Like polyester, rayon is super durable.
- Breath ability: Rayon is exceptionally breathable, as well as absorbent.
- Softness: Rayon looks and feels incredibly soft and silky, and has a lustrous sheen.
- Colorfastness: Unlike some wool and cottons, rayon holds color very well and resists fading.
The best socks combine a blend of both polyester and rayon. This combination provides superior strength and durability from both materials, plus super-quick drying capabilities (from polyester) and superior absorbency and breathability (from rayon).
