Technical Underwear for Men

Introduction

Technical underwear is the foundation of good insulation during activities in extreme cold. In the men's sports clothing section, they help wick moisture, limit odors, and retain heat without overheating.

Which materials to choose?

Merino wool: natural, warm, and naturally odor-resistant. Ideal as mid-layers and base layers.

Synthetics (polyester, polyamide, polypropylene): very effective at wicking sweat and drying quickly. Often more durable for intensive use.

Blends with elastane: provide elasticity and support. Prefer fabrics with a weight suitable for your activity.

Practical advice: before buying, compare with our selection of trail t-shirts to find the right breathability and weight.

Styles and cuts

We distinguish: tank tops and lightweight t-shirts for intense efforts, long-sleeve models for cool weather, and technical bottoms for men to enhance leg protection. For sliding sports, opt for high-performance ski tights designed to stay close to the body without hindering movement.

Where to buy and services

If you're in a hurry, check out the men's hiking pants with express delivery and pair them with a suitable base layer. Also discover the technical underwear collection for men for a wide choice of weights and cuts.

Brands and equipment

For the mountains, consider Ortovox safety equipment and technical textiles that complement a high-performance base layer well. The Millet outdoor collection also offers products suitable for long outings and difficult conditions. To compare, we offer a selection of Odlo technical underwear in our product guide.

Care and lifespan

Washing: cold wash or 30 °C, delicate cycle. Avoid fabric softener which clogs technical fibers.

Drying: air drying recommended. A tumble dryer can damage anti-odor treatments.

Frequency: wash after very sweaty outings. Properly maintained, these garments retain their qualities for several seasons.

At what temperatures are they effective?

Lightweight: for intense activities above 0 °C.

Mid-weight: for temperatures between 0 and -10 °C depending on effort and outer layer.

Thick / thermal: effective from -10 °C to -30 °C when paired with adequate insulation.

Below -30 °C: multiple layers are needed, adding insulation and external protection.
