For wool products, airing rather than washing is sometimes sufficient.
Wool is naturally fire-retardant, highly resistant to bacteria and mould.

UphillSport® is an outdoor lifestyle brand originating from Finland, renowned for its high-performance socks specifically engineered for extreme outdoor conditions. Rooted in the Tampere region—an area with over 200 years of rich textile manufacturing heritage—UphillSport benefits from unparalleled craftsmanship and innovation in textile production.

The brand is created and produced by Sukkamestarit Ltd, a Finnish company with a long-standing history in sock manufacturing since 1996. Leveraging decades of expertise, Sukkamestarit has honed advanced techniques to produce premium performance socks capable of withstanding the harsh, cold, and moist sub-Arctic climates typical of northern Finland.

Launched in 2014, the UphillSport® brand combines traditional textile heritage with cutting-edge technology, focusing on multi-layer sock systems that maximize breathability, moisture management, durability, and warmth. Each pair of UphillSport socks undergoes rigorous Arctic testing to ensure reliability in extreme weather conditions, making them a trusted choice for outdoor enthusiasts, athletes, and professionals alike.

UphillSport's product range includes specialized socks for hiking, running, skiing, fishing, and workwear, designed to provide unparalleled comfort and protection on any adventure—from Arctic expeditions to rugged Australian treks. The brand’s commitment to innovation and quality is further exemplified by its military-grade performance credentials, such as being worn during the Netherlands Marine Corps’ world record speed march under freezing temperatures.

Today, UphillSport stands as a premium sock brand that seamlessly blends Finnish tradition with modern technological innovation, dedicated to delivering durable, multi-layered socks that keep feet dry, warm, and supported no matter the challenge.

UphillSport® has revolutionized outdoor and performance socks through their pioneering Multi-layer System technology. At the heart of their innovation is a carefully engineered technical multilayer structure that allows the creation of socks that are remarkably warm while maintaining a slim and lightweight profile. Unlike traditional thick socks that rely solely on bulk to provide insulation, UphillSport® leverages the unique properties of different materials layered strategically to optimize performance.

This approach ensures that UphillSport® socks effectively regulate temperature and keep feet dry, even during intense physical activities or in extreme outdoor environments.

Care instructions:

pre-wash merino wool socks before use

use as light a spin as possible
the use of a wash bag saves wear and tear
do not use detergents containing rinsing agents or bleaching agents
do not use a tumble dryer or drying programmes
please note that merino wool socks will shrink in the wash, please shape/stretch the socks while damp to restore the original size
use a lint remover - merino wool socks are easily linted by rubbing

Lifestyle Patterns Socks I Merino Wool I UphillSport

Paul Stephen

The Perfect Mix of Style and Performance

I wore the Lifestyle Patterns Socks throughout my Japan adventure, from exploring waterfalls and scenic trails to an overnight climb of Mount Fuji, Japan’s highest mountain at 3,776m. Taking on the mountain with around 1,700m of elevation gain and staying overnight in a mountain hut, these socks provided the comfort and reliability I needed for long days on the trail. The merino wool helped regulate temperature and kept my feet feeling fresh, while the fun designs added a unique touch of personality to my hiking gear. A perfect combination of performance, comfort, and style for any adventure!

Paul Stephen

All-Day Comfort Above 3,000m

I put the Combat Tactical Socks to the test on an overnight hike up Mount Kita, Japan's second-highest mountain at 3,193m. With around 1,600m of elevation gain, it was a demanding climb, but these socks performed flawlessly. They were comfortable, supportive, and stayed in place over the steep, rocky terrain, while the merino wool kept my feet feeling fresh across both days. I'd happily trust them on any challenging hike.

Excellent Performance on Volcanic Trails

I wore the Posio Trekking Socks throughout my hiking trip in Japan, including the volcanic trails of Aso Kuju National Park, and they were outstanding. They were comfortable all day, provided great cushioning, stayed in place, and kept my feet dry and blister-free despite long hours on the trail. Easily some of the best hiking socks I've worn, and I'll definitely be taking them on future adventures.
