SM500 Hydro-Block Waterproof Sock (Boot Cut)

The Hydro‑Block Medium Weight Waterproof Sock is engineered for anglers and hunters who refuse to let cold, wet conditions slow them down. Built with a 100% waterproof, breathable membrane, it delivers 8,000mm waterproof protection to block heavy rain, stream splash, wet brush, and even pressure from leaking boots or waders. A 10,000g breathability rating releases heat and sweat vapor so your feet stay dry from the inside out—no swamp‑foot, no overheating, just steady comfort all day.

Inside, a Merino wool liner adds warmth, softness, and natural moisture control, while the 3‑layer construction provides durable, medium‑weight insulation ideal for long days on the water or in the field. Whether you’re cold‑water wade fishing, trekking through rain, or pushing through soaked terrain, Hydro‑Block keeps your feet Bone Dry. Warm. Ready. Better protection means better hunt‑fish days—guaranteed.
