Product details

The original mid-length sock Billockby is 100% waterproof with Hydrostop.

  • Outer layer: 94% nylon, 6% elastane. Extra durable nylon with 4-way stretch for a perfect fit.
  • Middle layer: Aquasealz waterproof membrane. 100% waterproof and breathable, ensuring that internal moisture does not build up inside.
  • Inner layer: 75% bamboo rayon, 23% nylon, 2% elastane. Bamboo lining for better moisture control.
  • Hydrostop is an elastic band around the inner cuff of the sock. This extra barrier reduces the chance of water running down the leg inside the sock.
  • Care guide: Wash at 40°C, tumble dry on low or drip dry. Do not dry clean, do not iron, do not use bleach.
