BRIDGEDALE Expedition Heavyweight Merino Performance Sock

Engineered for the world’s most demanding adventures, the BRIDGEDALE Expedition Heavyweight Merino Performance sock stands as the ultimate companion for cold-weather expeditions. Built for serious explorers, this expedition sock delivers extra warmth, exceptional impact resistance, and all-day comfort through advanced cushioning and a sophisticated zonal padding system—critical for long treks, high mountains, and winter conditions.

Made with Merino Performance Fusion Technology, the sock features a blend of 28% merino wool, 19% new wool, 34% nylon, 18% Endurofil polypropylene, and 1% Lycra. This combination ensures resilient padding, balanced insulation, superior moisture-wicking, and outstanding durability, keeping your feet cozy and protected even in the toughest environments.

The Performance Fit is designed to remain close and supportive, resisting slip or bunching, while the insulated flat toe seam prevents cold spots. The Elasticated Arch and 3D-shaped heel cup keep the sock securely in place, and the structure of Lycra, set through the Thermo Fit process, ensures the sock retains its original shape and size wash after wash.

Tested by explorers in the coldest, most extreme locations on the planet, this heavyweight crew sock is the ideal choice for backpacking, mountaineering, skiing, and multi-day treks—delivering comfort, warmth, and reliability when it matters most.
