37.5 Technology is a brand created by Cocona Labs and probably not one you would have heard about or heard much about. It is not because it isn’t a success, but because other companies use the technology it creates that you will have heard about. Jeremy Webb tests some products incorporating 37.5 Technology and discovers how this innovative idea benefits many people.

37.5® Technology utilises natural volcanic minerals permanently incorporated into fabrics, insulations, foams, and laminate materials. The patented technology is proven to help you stay comfortable and perform at your best by helping the body maintain an optimal temperature and relative humidity next to the skin, regardless of the activity. Materials made with 37.5 Technology offer sustainability benefits throughout the product lifecycle and are used across various industries, including apparel, footwear, bedding and home goods.

In 1992, while in Japan, the creator of 37.5 Technology visited the volcanic sand baths on Mt. Aso. He believed he would only be able to stand the heat for a few minutes but found that when buried in the sand, he was comfortable with the heat and stayed for one hour. He realised that comfort comes from balancing heat gain and heat loss. The volcanic sand was removing the sweat vapour from his skin so fast that he was continually cooled by sweat evaporation.

It was the moment of clarity; he understood that removing the sweat vapour before turning it into liquid sweat was key to comfort. While others were focused on wicking—spreading liquid sweat on fabric—he focused on reducing humidity next to the skin to maximise evaporative cooling. And it turned out that by enhancing comfort, human performance was increased by reducing core temperature buildup. You can experience the same phenomena when wearing apparel and footwear made with 37.5 Technology.

Your performance and comfort depend on maintaining an ideal core temperature of ~37.5°C and a relative next-to-skin humidity of 37.5%. 37.5 Technology does just that. The thermoregulating fabrics and materials help you stay at a comfy ~37.5°C and 37% humidity level, no matter how hard you charge.

37.5 Technology provides,

Better Performance

Scientifically proven to increase stamina by reducing the energy used to manage core temperature, 37.5 Technology extends an athlete’s peak performance by 10 minutes—or 26%. It increases efficiency, so you use less energy to do the same amount of work.

Better Sleep

Proven to reduce the effect of temperature-induced sleep disruptions, 37.5 Technology leads to longer, more restful sleep cycles, so you stay in your comfort zone more often and longer: 89% of the time vs only 38% with traditional materials.

Less Moisture

37.5 technology removes moisture in the sweat vapour stage before liquid sweat forms. Wicking only distributes moisture, so 37.5 keeps you drier and more comfortable than wicking.

Balanced Temperature

Using your body’s energy to speed evaporation and remove humidity next to your skin, 37.5 Technology adapts to help cool you when you’re hot or keep you warm when you’re cold.

Natural Active Particles

37.5® Technology permanently incorporates ultra-porous volcanic minerals and coconut-derived activated carbon into fabrics, insulations, foams, and laminate materials using our proprietary process.

Powered by Your Own Energy

The temperature-regulating materials powered by 37.5 Technology absorb the infrared (IR) energy your body naturally emits, which energises our active particles to speed evaporation and remove humidity next to your skin.

Increased Surface Area

The billions of micro-pores in 37.5 active particles massively increase the surface area of fibres and other materials to remove moisture at the vapour stage—before you even break a sweat. Unlike wicking materials that distribute moisture, the temperature-regulating fabrics and materials with 37.5 Technology remove it.

Many brands are using 37.5 technology, and the following are a few.

Furygan 37.5 Active Cool Base Layers.

37.5 Cool.

Furygan, the French motorcycle clothing brand, manufactures equipment and products to protect all body areas. One of their latest ranges is 37.5 Active, which includes Active long-sleeve tops and full-length pants in both Cool and Thermo. We tested the Cool range as the daytime temperatures started to rise, and we wanted to see if our bodies didn’t.

As Spring arrives, we hope for warmer weather and fewer layers when riding. It is always preferable to wear comfortable clothing and not be Goldilocks, too hot or too cold, and the best way to achieve this is by using base layers. Modern base layers are far more than wearing a T-shirt under a sweatshirt; they have technology incorporated into the fabric that, in winter, will keep your body warm and, in summer, cool without sweating and without that awful wetness between your skin and clothing.

When riding, you must focus on the road, traffic, and all elements, so distractions from discomfort and issues caused by your clothing are unwanted. The 37.5 Active clothing prevents interfering thoughts caused by being too hot or cold.

37.5 is underwear for bikers who want to optimise their riding experience. 37.5® keeps the body dry regardless of the climate and level of intensity. The compression zones and seamless design provide perfect support and eliminate chafing. It is a must-have as soon as the summer heat sets in.

The active 37.5® particles, permanently integrated into the weave, give our fabrics an extraordinary capacity to capture and clear humidity by acting with the body like a natural thermostat.

The TECHNOLOGY?

37.5® is a thermoregulation technology that interacts with the body and triggers off of humidity. It’s powered by naturally occurring, activated particles.

HOW DOES IT WORK?

37.5® technology is dynamic – it works with your body to determine whether you need to be warmed or cooled based on the amount of moisture present, which is the body’s way of expressing whether it’s hot or cold. 37.5® particles capture the infrared (IR) energy emitted by your body, and if moisture is present, they speed up evaporation to cool you down. If no moisture is present, the IR energy is used to help you stay warm. In all cases, it’s a question of managing the amount of moisture close to the skin, which regulates comfort.

HOW LONG WILL IT LAST?

37.5® Technology is a permanent technology that will last the product's lifetime. It’s not a chemical finish; the natural particles are embedded in the yarns or fibres and will never wash out.

THE TECHNOLOGY

The exclusive 37.5® technology uses active particles made from volcanic rock. These particles attract water vapour and draw it away from the garment, keeping your limbs drier for longer so you can enjoy your ride, however long it may be.

Seamless design for a perfectly smooth, snug fit all over the body. This process guarantees superior comfort without discomfort or skin irritation from rubbing during intense activity.

The design includes zones with different levels of elasticity. The benefits are a sheathing effect and support for the body in all movements.

Design based on the ergonomics developed for our world’s best racers.

To allow a perfect fit thanks to its superior elasticity.

For a garment that fits perfectly, the selection of materials, assembly techniques, and cut-outs' layout have been designed to provide maximum performance without ever creating any discomfort when worn.

Designed with materials with a high capacity to dry quickly to avoid uncomfortable residual moisture sensations

The 37.5 Active Cool range proved magnificent in its performance when we wore it in changeable spring conditions. Setting out early, even on a sunny blue sky day, can mean temperatures around freezing, but the base layers against your skin act as a splendid thermal barrier to stop you from getting too cold. When the day progresses and the temperatures increase outside, they also increase inside your clothing. The 37.5 technology then kicks in to prevent moisture build-up and sweating. We all agree that you need at least one pair of the Furygan 37.5 pants and one of the Active Long-Sleeve tops.

The Active Long Sleeve Cool Top is £69.90, and the Active Cool Pants are £59.90
