35 Below

When it’s cold outside, keeping your feet warm is a top priority. That’s where 35 Below comes in. This brand is all about creating the best thermal socks to help you brave the elements in style and comfort.

About 35 Below

35 Below is a leading manufacturer of high-quality thermal socks and apparel designed to keep feet warm in even freezing temperatures. The Minnesota-based company has been creating innovative cold weather gear since 1936 when founder Henry Jones first developed the concept of thermal socks.

Frustrated by inadequate socks that left his toes frostbitten during Minnesota winters, Henry began experimenting with different materials and techniques until perfecting a sock that regulated temperature and wicked away moisture. His invention was an immediate success locally and soon spread across the northern United States.

Over the decades, 35 Below has expanded its product line while remaining dedicated to its mission of providing the warmest, most comfortable socks and clothing. In addition to their signature thermal socks, they now offer gloves, hats, and gaiters made from advanced fabrics like Thermalite® and Thermacushion®. Their use of premium Merino wool and technical synthetic fibers ensures uncompromising quality.

While primarily known for socks, 35 Below has also applied their expertise to lightweight seasonal socks and athletic footwear. However, their classic thermal socks in styles for men, women and children remain their most iconic product. With a dedication to research, responsible manufacturing, and customer satisfaction, they have established themselves as the premier brand for cold weather comfort.

35 Below prides itself on keeping the entire family’s feet warm throughout winter. Their innovative fabrics, extensive sizing, and fashionable designs make them the ideal choice from the fireplace to the ski slope. While serious about socks, their playful brand personality also shines through. As a Minnesota-based American company, 35 Below delivers warmth and comfort you can feel good about.

I've lived in Montana my whole life and know a thing or two about cold winters. For years I struggled to find socks that could withstand our below freezing temps but still be comfortable. Most were either too bulky or didn't retain heat well. Then I discovered 35 Below thermal socks. I bought my first pair 2 years ago and now won't wear anything else! The Thermalite fabric has the perfect thickness to be warm but not bulky in boots. After hours out snowmobiling my feet stay toasty. I also love the cushioned footbed that prevents fatigue. For winter mountain activities, 35 Below socks can't be beat. I've tried other brands but nothing compares to the consistent quality and comfort 35 Below delivers.

Living in New England means I need socks that can endure cold, wet winters. 35 Below's thermal socks have worked great for me! I walk my dog every morning before work, even on snowy days, and my feet stay warm and dry the whole time. I love the soft Merino wool - it's so much more comfortable than other wool socks I've tried. The snug fit around the ankles also prevents snow getting in my boots. As a busy teacher and mom, comfort is crucial. I'm on my feet all day and appreciate that 35 Below socks don't pinch or rub my feet raw. Their durability is amazing too. After 2 years of heavy wear, they still look and feel new. For winter comfort you can rely on, I highly recommend 35 Below. Worth every penny!

I work outside year round in Alaska so finding good thermal socks is a must! 35 Below socks are the best I've come across. They stand up to heavy use day after day. The Thermacushion padding makes my work boots much more comfortable and reduces foot fatigue. Even at the end of a 12 hour construction shift, my feet still feel good. The socks also retain heat well even when damp. I accidentally left a pair outside overnight in rain and they were still warm and toasty the next morning. For the extreme Alaska climate, 35 Below socks deliver. They also hold up well to repeated washing without losing their shape or warmth. For heavy duty insulation you can depend on, I would definitely recommend trying 35 Below. Your feet will thank you!

As a Minnesota native, I know how important quality socks are! I bought some 35 Below socks last winter and have been so impressed. They are so soft and comfortable - I love the premium merino wool. It regulates temperature well as I move between indoors and outdoors. The anti-microbial treatment also keeps my feet smelling fresh all day. I work in an office but walk to lunch and errands. The Thermalite fabric wicks moisture well so my feet never feel soggy. The socks retain their shape and elasticity after many wears and washes too. With kids, I need socks that stand up to frequent laundering! 35 Below has become my go-to brand for winter. From casual around-the-house to outdoor activities, their socks keep me warm in every situation. Well worth the investment for such excellent quality and comfort.

I tried 35 Below socks last winter and was amazed at the difference from other brands. During long days ice fishing, my feet stayed warm and comfortable even in subzero temps. The Thermacushion padding prevents my feet from getting sore and numb sitting on the frozen lake all day. The socks don't bunch up in my boots like so many other brands. I'm very active and appreciate that they absorb sweat and moisture when I'm snowshoeing or cross-country skiing too. The socks clean up nicely after multiple wears. Even after many washes, the fit is snug and supportive. With the quality construction, these socks seem like they'll last forever. For keeping active in frigid Wisconsin winters, I can't recommend 35 Below thermal socks enough. They've made a huge difference in my cold weather comfort. Well worth the investment!
