Key technologies and functionality:

How did we create the most thermally efficient base layer on Earth?

Defined the 6 Goals:

To develop the world's most efficient natural moisture management technology.
To make a textile that absorbs and wicks moisture from the skin better than any other.
To create chemical-free odor-elimination and antibacterial fabric for hunting.
Design the coziest natural fiber clothing, crafted to be gentle, even on baby skin.
Maximize thermal insulation by using the finest yarns, which trap significantly more air than the thicker yarns used by our competitors.
To deliver a durable, long-lasting material you can trust.

What is SYNERTECH?

The synergistic technology developed by Hillman combines the best functionalities of two or more materials, achieving exponentially higher results than each material used separately. For example, we use bamboo fiber as the most efficient moisture absorber and merino wool as the most efficient wicking fiber.
In comparison, we can't reach such a high efficiency level for moisture absorption and wick by using the materials separately.

What happens if the clothing is made only of Merino wool?

Even when we use its best quality of 15.5 microns, the Merino wool structure is coarse and can only absorb 30% of its weight in moisture. Nevertheless, it stands out as the most effective moisture-wicking material on Earth.

Practically, if you wear Merino wool, it will effectively manage moderate sweating but may struggle to absorb excessive moisture from your skin, resulting in a wet and sticky feeling on top of your skin. For example, it won't absorb moisture when you are actively running or walking, and you will develop underarm sweat on your skin that takes a longer time to be absorbed.

Furthermore, merino will cause itching on sensitive skin, irrespective of its quality, grade, and origin.

What happens if the clothing is made only of Bamboo viscose?

Bamboo viscose is a natural antibacterial hollow fiber that absorbs moisture three times its weight, three times faster than cotton, and ten times better than wool. It can wick moisture faster than cotton but is less efficient than wool.

odor elimination hunting anti-odor baslayer

For example, bamboo will absorb your sweat much quicker than any other material, but you will still develop sweat spots, which will be fewer than cotton but still exist.
Also, bamboo fiber provides a silk-like, gentle feeling when in contact with the skin. It also allows heavy brushing for superior air trapping, better insolation, and a gentle fleecy feel.

The Final Result

Using natural chemical-free bamboo fiber as the best moisture absorber and the World’s finest possible grade 15.5-micron Australian merino wool as the best moisture-wicking layer, we have exponentially higher moisture management and thermoregulation efficiency than any other material on Earth. By using the finest grades of materials, the gentle and cozy, itch-free, super functional fabric is now a reality. The plus is that both fibers are naturally antibacterial and anti-odor, making them the best synergy of natural fibers for hunting clothing ever.

COATS PROTECT

the power of anti-odor and anti-bacterial threads

Even if the material is antibacterial, the odor buildup in the underarm threads will always occur if the threads are not treated. This is why we used the one-of-a-kind CoatsProtect® threads to sew our hoodie and achieve the maximum level of odor elimination.

With anti-microbe treatment

GET INTO THE SCIENCE OF MERINO WOOL - THE FIBER THAT’S WORTH IT

Before we made our own, we used to buy all other products out there, all the while wanting different, better clothes to keep us warm in winter and cool in summer. But we still got cold, wet or clammy, not to mention that we’d stink more often than not. After years of research, we were led to an old favorite of our grandparents — wool. It helped keep us warm all winter and remarkably cool in the summer, without the stink. However, that wool wasn’t very comfortable. Then we discovered Merino wool and our world was changed forever.

THE KEY FACTORS OF QUALITY AND HOW TO BE ADEPT WHEN BUYING

Merino wool is able to ditch the itch thanks to its fiber’s smaller diameter. The finer fibers are more flexible and softly bend when pressed against the skin, and therefore don’t itch like other wool fabrics. These also enhance the wool’s elastic nature, making garments made with Merino wool more able to conform to the body shape they’re on, enhancing the garment’s performance and the wearer’s comfort.

How we invented the world’s best Merino layers ever made for hunting

▼

USING THE FINEST WOOL THE WORLD HAS TO OFFER
Our Merino products are the finest that current technology allows. Why do we say technology? Because the superfine merino fibers are extremely difficult to master, we needed novel methods to keep the fibers stable like they are in blends. Hillman’s Merino fiber is so fine, with a gentle cotton-like touch, instantly offering much greater comfort, far higher functionality, and efficiency for thermal insulation than any other Merino available today.

▼

CREATING A FLAWLESS BODY MAP SYSTEM
Imagine having an exceptionally warm layer of Merino, and now imagine it doubling under your arms as soon as you retract them to your body. Yes, more Merino doesn’t always make for better comfort, or at least not in this case. The same happens with your thigh area. What about the pant cuffs? Imagine always having to squash them into your boots... Now, do you get what body-mapping is? With the help of our BodyMap technology, you will be equipped with heavier fabric in areas where extra warmth is needed and with a lighter one where mobility is essential. Don’t worry; we also thought about your pant cuffs, which we thoughtfully designed with a break above the shoe area.

▼

IMPLEMENTING TECHNOLOGIES FOR COMFORT
In order to create our clothing versatile, valuable and true to its purpose, we implemented various technologies throughout the process. From flat seams, thumb holes, pockets, and others to superb seamless sewing, stretch zippers, and heating system integration, it’s a process that we’ve been developing for years. Today, we can, without a doubt, declare that our Merino layers will bring you new levels of comfort, functionality, and satisfaction since they’re invented exclusively with you in mind.
