Breaking away from the conventional idea that a cap is just a physical object, the UL Merino X Cap 2026 model is made with 100% merino wool .

This has resulted in improved breathability, odor resistance, and a soft feel against the skin, making the hat even more natural and comfortable to wear .

The "natural comfort" of merino wool

Merino wool is a natural material that contains tiny, invisible layers of air within each fiber.

This structure provides excellent moisture control and breathability , preventing stuffiness even when you sweat and preventing outside air from building up .

It responds to changes in body temperature, providing natural temperature regulation by keeping you cool when it's hot and warm when it's cold .

Furthermore, the keratin protein on the surface of the wool absorbs and neutralizes the sweat and sebum components that cause odor , so it functions as a natural odor-preventing material, preventing odor even after wearing it for days .
You'll stay comfortable even on long hikes or trips.

Knit construction provides airy ventilation

Typical merino wool fabrics have excellent heat retention and moisture control properties, making them very comfortable to wear. The dense weave structure makes it difficult for wind to pass through, and in hot and humid environments like the Japanese summer, heat can easily build up around the head. It's not really suitable as a hat.

The UL Merino X Cap has a unique knitted structure made from merino wool yarn, which creates tiny gaps that allow air to escape like a mesh, creating breathability .

The result is amazing comfort and resistance to stuffiness, even on ridges in the middle of summer or on humid days .

Sustainable materials that are kind to both people and the earth

Merino wool is a renewable natural fiber and is also an earth-friendly , sustainable material that meets the SDGs .

This is a truly modern UL cap that embodies the hiker's values ​​of being "light, comfortable, and natural" and is in line with the cycle of nature .

You can feel the soft texture when you touch it, and it has an airy fit that feels like it contains air.

You will feel a sense of openness, as if you are not wearing anything .

Surprisingly light

The soft and gentle feel of 100% merino wool further enhances the airy impression.

By eliminating the polyester thread, the entire cap is even lighter.

The 2026 model offers an even more stress-free fit, so comfortable you'll forget you're wearing it .

Since the first model, the peak has been made of the lightweight waterproof fabric X-Pac®, and by deliberately omitting the core material found in ordinary caps, it has achieved the ideal ultra-lightweight design .

In addition, the sweatband is made of extremely thin fabric to eliminate unnecessary bulk.

Eliminating unnecessary thickness and weight around the head also contributes to a feeling of lightness.

In addition, the parts for fine-tuning the size at the rear were also selected with an emphasis on lightness.

Every detail has been made lightweight, making this cap comfortable to wear even when worn for long periods of time. It has been finished in this way.

A comfortable fit that doesn't constrict

The body is made of 100% merino wool and is characterized by its soft, conforming fit to the shape of your head, rather than being stiff and restricting it.

Rather than pressing tightly, it feels like it gently hugs you , making it less stressful even when you're out and about for long periods of time.

In addition, the adjustable part at the back allows for fine adjustments, so you can get the fit you want while still maintaining a balance that is not too tight .

It is designed to be comfortable to wear even during long hikes or long-distance trekking, where you sweat, dry, and then start walking again.

Even on summer hikes where sweating is unavoidable, keep your forehead as comfortable as possible.

With this in mind, the sweat-absorbing part that comes into direct contact with the skin has been designed with Lawn fabric is a blend of natural cotton and linen. We have adopted the following.

The parts that come into contact with the skin are made of natural materials

Instead of using the synthetic COOLMAX® sweat-absorbing material commonly used in sports caps, we have chosen natural fibers that are soft and gentle on the skin in order to reduce stuffiness and itching on the forehead, even if only a little.

Woven from fine yarn, lawn is very thin, highly breathable, light, and smooth to the touch .

Easy to dry and stays clean

In addition, the hemp content makes it less susceptible to bacterial growth and allows the fabric to dry quickly even when wet .

Even when you are active for long periods of time, your forehead will not feel sticky and you can continue to wear it without any stress .

The gentleness of natural materials supports comfort in invisible areas.

A cap that you can wear naturally anywhere.

The UL Merino X Cap strikes a balance between function and design , making it at home on a mountain ridge or in a local cafe.

Minimalist design that highlights X-Pac®

The back strap is made of X-Pac®, the same waterproof material as the visor.

The uniform coloring and texture make this a design that is suitable for both outdoor and urban use .

Functional in the mountains, casually stylish in the city.

Goes great with helmets and knit caps

The soft merino wool body is comfortable to wear over a helmet or knit cap , making it ideal for layering in cold weather.
