The most sophisticated base layer in Assos history was born.

This season, the base layer of ASSOS has reviewed the materials and manufacturing method from the beginning, and has entered a stage that is one rank higher than the conventional SKIN FOIL in all performances.

Of the new seriesSKIN LAYER / skin layerIs the first layer that comes into contact with the skin, that is, the base layer is the most important item for adjusting the metabolic function, and Assos has always been devoted to material development. The latest answer is the adoption of a unique carbon fiber blended fiber that dries quickly and has excellent antibacterial activity. And the body woven into a tube by the circular seamless manufacturing method fits the skin with uniform tension.

The secret lies in the uneven borderline

If you look closely, the fine border line applied to the whole has a three-dimensional uneven structure, and while the part in close contact with the skin promotes sweat treatment, a heat insulating layer of air is formed in the part slightly away from the skin. Now you can feel dry and comfortable under any conditions.

Three actions by carbon fiber
"Lightness", "durability", "antibacterial action"

The benefits of reviewing the manufacturing method are not limited to that, and by weaving carbon fiber, we have achieved a weight reduction of 10% compared to the previous work without compromising durability. The lightness, which is as fluffy as feathers, keeps other base layers away. In addition, the antibacterial action of carbon fiber has the function of suppressing the growth of bacteria that cause odors.

Wool blended to the depths of the body

ULTRAZ WINTER SKIN LAYER boasts overwhelming cold protection in the new SKIN LAYER series. Wool, which accounts for 30% of the total, is blended to fill the gaps in the synthetic fibers, demonstrating the maximum heat capacity. It also has windproof properties due to its high-density fiber structure. It is a base layer that feels warm to the depths of the body, which is not recommended for those who are hot.

The base layer is one of the important items to protect your body when cycling in winter. This is because the wind that is exposed while driving in winter, which is different from that in summer, becomes a ferocious cold air that freezes the body. The cold wind deprives the body of heat, and the cold sweat repels it. ULTRAZ WINTER LS SKIN LAYER is made of a thick knit fabric that is a blend of polypropylene and wool prepared for the severe winter season when such adverse conditions overlap. While accumulating body temperature closest to the skin, sweat can be smoothly transferred to the outerwear. In addition to the comfortable warmth unique to wool, it also has the property that sweat is cold and hard to feel. Recommended for those who are cold or who live in cold areas along the mountains. In addition, it is a base layer that you can use with confidence even in scenes where you run without increasing the strength too much.

The high neck also has the effect of not cooling the internal organs

The high neck that covers the neck is surprisingly effective, and by not exposing the neck to the outside air, it does not cool the blood flow and protects the heart, which is the engine of the body.

Separate sizes for men and women and silhouettes

Previously, the base layer of ASSOS was unisex, but from the SKIN LAYER series, it is now available in different sizes for men and women. In consideration of the difference in skeleton between men and women, men's shoulders have a straight box silhouette. Ladies have raglan sleeves with rounded shoulders. The elasticity of the material is very high, so if you prefer a tight fit, we recommend a smaller size than recommended by the manufacturer.
