Darn Tough Men's Coolmax Hiker Midweight Crew

Your Feet's Personal Air Conditioner.

Heat on the trail comes in many forms — hot and humid, dry and searing, or just plain relentless. The Darn Tough Men's Coolmax Hiker Midweight Crew (Style 1931) in Black Gray is engineered to handle all of it. Built around Coolmax® engineered yarns, this sock actively moves heat and moisture away from your skin, keeping your feet cooler and drier on even the balmiest days on the trail.

Coolmax® Technology

Coolmax® is one of the most trusted moisture-management technologies in performance apparel, and Darn Tough has woven it directly into this sock's construction. The engineered fiber structure increases surface area to accelerate evaporation, pulling sweat away from the skin faster than standard fabrics and dispersing it so it dries quickly. The result is a noticeably cooler, more comfortable foot environment mile after mile.

Midweight Cushioning for the Long Haul

Despite its cooling focus, this isn't a bare-bones ultralight sock. The midweight construction provides meaningful cushioning underfoot — enough to absorb impact on rocky terrain and reduce fatigue on extended hikes, without trapping the heat that heavier socks can generate. It's the right balance for hikers who want comfort and performance in the same package.

Micro Crew Height

The micro crew height sits just above the ankle, providing coverage and protection against boot collar abrasion without adding unnecessary bulk. It pairs naturally with hiking shoes, hiking boots, and trail runners — versatile enough for whatever footwear your trail demands.

Darn Tough's Unconditional Lifetime Guarantee

Knit in Vermont from a Merino wool and Coolmax® blend, this sock is backed by Darn Tough's unconditional lifetime guarantee. If it ever wears out, they replace it — no questions, no receipts required.
