Relaxsan Zero°: Dryarn® and Merino Wool thermal underwear that works like a second skin

Facing the coldest months or transitional seasons requires smart clothing. Whether it is for outdoor sports, working outside, or simply handling daily life with maximum comfort, choosing the right base layer—the first layer in contact with the skin—is essential.

To meet this need, the Relaxsan Zero° line was created: a high-performance technical thermal underwear that combines the benefits of the best fibers found in nature and on the market.

The “Double Layer” Revolution: How Does It Work?

The secret of the Relaxsan Zero° line lies in its innovative double-layer construction, designed to create a perfect microclimate between the body and the external environment:

• The Internal Dryarn® Layer: In direct contact with the skin, we find Dryarn® microfiber. This fiber is 30% lighter than polyester and provides 20% higher breathability than other fibers. Its job is to capture moisture and sweat generated by the body and instantly transfer them to the outside, keeping the skin dry and thermoregulated at all times. Additionally, it is dermatologically tested to prevent irritation.

• The External Merino Wool Layer: The outer part of the garment is made of the finest Merino wool, a 100% natural, soft, and elastic fiber. Its function is to provide thermal insulation, protecting the body from the cold while encouraging the evaporation of moisture pushed outward by the Dryarn®.

Two Weights for Every Climate Need

To adapt perfectly to different temperatures and intensities of use, Relaxsan Zero° garments—available in various models including T-shirts, long-sleeved shirts, turtlenecks, and leggings—are offered in two different fabric weights:

• 150g Fabric (Mid-Season and Daily Use): Ideal for transitional seasons like autumn and spring, or for those living in environments that are not extremely cold. This weight is perfect for wearing as a first layer under everyday clothing or during moderate sporting activity. It helps prevent the temperature fluctuations typical of seasonal changes.

• 250g Fabric (Winter and Intense Cold): The ultimate solution for harsh winters. This heavier weight is designed for those who practice prolonged sports at low temperatures (such as skiing), for those who work outdoors, or for those who need natural “thermotherapy” to relieve muscle or joint pain thanks to the heat retained by the garment.

Benefits for Sport and Lifestyle

Choosing the Relaxsan Zero° line means not having to compromise between warmth and freedom of movement. The main benefits include:

• “Second Skin” Effect: Thanks to a small percentage of elastic fiber, the garments adapt softly and ergonomically to the body’s shape.

• Seamless Technology: The absence of annoying seams ensures absolute comfort and total freedom of movement, preventing chafing during physical activity.

• Thin and Practical: Despite high thermal insulation, the fabric remains thin, allowing for layering without feeling weighed down.

• Simple Maintenance: The specific materials used allow for easy washing and, above all, extremely fast drying.
