Massdrop x Fitsok Merino Socks: Earth 3-Pack

Driven to make an everyday sock that fits better, feels better, and keeps you comfortable mile after mile, we teamed up with Fitsok: a US company that has changed what we can expect from the classic 3-pack. These new earth-toned colors are inspired by the season’s natural landscapes, full of soft browns and lush shades of green. All three styles—crew, hiker, and low-cut—are made of a soft, durable blend of American-dyed merino wool and nylon. These socks are technical enough for hiking, biking, running, and other active pursuits, with a clean aesthetic that’s well suited for daily wear.

Merino wool is naturally thermoregulating, which means it keeps you warm in cold weather and cool in warm weather, and prevents overheating and clamminess by absorbing and releasing vapor. It’s also naturally antibacterial and odor-resistant, so you can stretch an extra day out of your pair when you need to. The addition of nylon takes the durability up a notch, and the touch of Lycra adds just enough stretch. Light cushioning under the heel and toe areas provide support where you need it, while lighter mesh weave on the top improves breathability and fit. Plus, the arch compression creates a secure fit and improves comfort.

The Sock Factory—a premier performance sock manufacturer in North America—took root in 1975 when founder Michael Banks Sr. bought a couple of dye tubs and a dryer from his father. What started as a small operation quickly grew much larger, now employing a team of more than 50 (many of whom have been on staff for 15 years or more). Founded in 2007 and acquired by The Sock Factory in 2016, Fitsok focuses on engineered fit and performance socks made in the US. Still based in Hickory, North Carolina, the family-run business prides itself on quality footwear and top-tier customer service. Any pair of socks that doesn’t meet its strict standards is donated to local homeless shelters and nonprofit organizations.
