The ultimate sock for high altitude expedition use. Designed for hard shell mountaineering footwear and extended cold weather activities in extreme environments. Hand sewn and designed with specific left and right foot anatomical shapes for precise fit. This is the cutting edge of warmth technology!
Based on feedback we received from professional mountaineers and cold-weather athletes we learned that most wool socks on the market were too constrictive and maintained moisture during their activities. This can be dangerous in parts of the world where a wet foot can lead to hypothermia or other serious conditions. Our design team wanted to solve this problem by creating a sock that would be incredible warm and dry. We searched the globe to find materials and a construction process that provide the perfect combination of elasticity, support, and warmth. We found that perfect combination in Polartec Power Stretch and Primaloft Yarn.
Two Layers of Polartec Power Stretch on the outer layer of the sock provide warmth without increasing weight. The smooth outer layer is wind- and abrasion-resistant; the soft inner layer pulls moisture away from your skin keeping you dry, warm and comfortable.
The inner layer of Primaloft Yarn is made up of ultra-fine polyester fibers which are finer than cashmere, resulting in a luxuriously soft feel while providing unparalleled moisture wicking. When hiking, climbing or doing any aerobic activity, your body works up a sweat and emits heat and perspiration, but when you suddenly sit idle, you can easily start to freeze with an insulation that absorbs water. Primaloft fibers wick moisture away from the skin and trap body heat.
Tested above 8,000 meters by athletes in real world conditions, you won't find anything else like these.

Lorpen began as a small manufacturer of technical socks in the Basque region of Spain in the early 1980’s. Our founders were looking to make innovative and functional socks for walking and hiking enthusiasts. We are now a company with manufacturing facilities located on two continents and we sell our socks in more than 60 countries worldwide.
While we have experienced significant growth, our founders still manage the company with their original vision intact, “to produce the best technical socks for serious outdoor activities.”
It's not unusual for our designers to head out into the local mountains that surround our headquarters in the morning before returning to design socks in the afternoon. This is what makes Lorpen different. Our passion and commitment to excellence is a direct result of living and working in a natural environment.
Our vision also includes a commitment to preserve the environment in every aspect of business. This means that whenever possible we work with fibres that are created from sustainable and manageable resources. We also develop manufacturing processes that are sensitive to the environment and reduce the amount of post production waste at all levels.
All of this is accomplished while we continue to bring new products to the market that increase the users comfort and durability. We're driven by our passion to make the best socks in the world.
