Don’t let the “light” in the name fool you; this sock is no lightweight when it comes to comfort, durability and all the heavy-duty work you can throw at it. Our Light Tactical Crew is the perfect lightweight field sock. The 100% Merino wool interior provides excellent moisture control and comfort while the nylon exterior provides maximum durability and abrasion resistance. Berry Compliant. Cushioned footbed with mesh top and leg. Merino wool next to skin feels great and is naturally anti-microbial and flame resistant. Nylon reinforcement on the outside of the sock for increased durability. Heel Lock ® provides heel security that limits the chances of a blister when combined with a properly fit boot. Dynamic Toe Cup ® limits the amount of material in toe box to prevent bunching in a critical area of the foot. Knitted construction naturally moves the seam back from the sensitive toe area. Excellent thermal insulation and moisture control. Crew height rises just below the calf.
