FAQs

Clothing affects body temperature through its insulation, moisture management, breathability, and thermal regulation properties. Traditional fabrics may trap heat and moisture, leading to discomfort through over-insulation, moisture buildup and hindered temperature regulation. However, with an advanced textile technology like 37.5 Technology, clothing can instead actively transport water vapor away from the skin and speed evaporation. This enhances breathability and helps to maintain optimal humidity levels to prevent overheating or chilling.

Temperature regulating clothing is designed to actively manage your body’s microclimate to help keep you comfortable in any environment. In contrast to traditional fabrics that can lock in moisture, or wicking fabrics that simply spread it out, temperature regulating clothing with 37.5 Technology actually removes moisture at the vapor stage, helping to balance your temperature and keep you in your ideal comfort zone longer.

Your performance and comfort depend on maintaining an ideal core temperature close to 37.5°C, along with a relative next-to-skin humidity of around 37.5%. The temperature regulating clothing powered by 37.5 Technology does just that, helping you stay cooler when it’s hot and warmer when it’s cold, as well as maximizing performance during work or play. The active particles in 37.5 Technology also trap odor molecules and then release them in the wash, keeping clothes fresher, wear after wear. And because those particles are naturally derived, the 37.5 fibers used in clothing do not contain any harmful chemicals.

Temperature regulating bedding is designed to actively manage your body’s microclimate during sleep, helping to ensure optimal comfort and restfulness. Traditional bedding materials can trap heat and moisture, leading to discomfort and disrupted sleep. However, the temperature regulating bedding with 37.5 Technology features active particles derived from natural sources to capture and release moisture vapor, helping to maintain an ideal relative humidity in your sleep environment. Whether you’re a hot or cold sleeper, this dynamic temperature regulation can help you achieve a more comfortable and rejuvenating sleep experience.

Absolutely. Temperature regulating bedding powered by 37.5 Technology is proven to enhance sleep comfort. Testing at Inside Climate demonstrated a relative temperature balancing effect of 5 – 19° F (or 3 – 12° C) when the temperature regulating bedding products with 37.5 Technology were compared against standard bedding products. This means that you spend more than two times longer in your ideal comfort zone when you sleep in a bedding system featuring 37.5 Technology.

The best bedding to regulate temperature typically includes materials that actively manage heat and moisture, promoting a comfortable sleep environment. Breathable fabrics like cotton or linen  can allow for better airflow and moisture wicking, helping to prevent overheating. However, when 37.5 Technology’s natural active particles are embedded in these fabrics and other textile materials, water vapor is removed before it turns to sweat, offering a far more dynamic management of the microclimate between the fabric and your skin.

During winter, the 37.5 natural active particles used in temperature regulating sheets absorb your body’s infrared energy, powering the particles to remove moisture, helping to keep you warm and cozy throughout the night. In the summer months, the same technology works to cool you down by speeding evaporation to remove excess heat and moisture, allowing for a refreshing sleep experience. This unique ability to regulate temperature helps ensure that sheets and other bedding with 37.5 Technology provide the perfect balance of warmth in winter and coolness in summer, for a restful night’s sleep year-round.

The temperature regulating clothing with 37.5 Technology achieves these seemingly opposing actions by harnessing the power of active particles embedded within the fabric. These particles are derived from the natural sources of volcanic minerals and activated carbon from coconut shells. When you’re hot, the particles remove water vapor from next to your skin, effectively cooling you down by facilitating rapid evaporation. Conversely, when you’re cold, the particles absorb infrared energy emitted by your body, helping to keep you warm. This dynamic interaction between your body and the fabric helps ensure optimal temperature regulation in any environment, providing more lasting comfort and contributing to greater performance.

37.5 Technology speeds evaporation and removes humidity next to your skin, helping to balance your temperature and keeping you in your ideal comfort zone longer.

Yes, wear testing has confirmed users prefer wearing the temperature regulating clothing made with 37.5 Technology. In a third-party consumer study done by MESH01, 75% of testers preferred a technical tee shirt containing 37.5 Technology over their current favorite shirt.

37.5 Technology traps odors and releases them when laundered or cleaned. Users have found fabrics made with 37.5 Technology stay fresher, longer.

No. 37.5 Technology is made from naturally occurring volcanic minerals. It is not a chemical finish and does not contain harmful chemicals.

No. 37.5 active particles are permanently embedded at the fiber level, work for the life of the product, and will not wash out during laundering.

The human body produces heat 24 hours a day. The most important way to regulate temperature is through the release of moisture vapor from the skin as sweat. The temperature regulating fabrics made with 37.5 Technology use ultra-porous minerals to massively increase the fabric’s surface area, attracting and removing this heat and moisture before it can turn into sweat. Using your body’s own energy to speed evaporation and remove humidity next to your skin, this fabric technology adapts to help you stay cooler when it’s hot and warmer when it’s cold.

Trapped moisture in your clothing, footwear or bedding is an amplifier, making hot feel hotter and cold feel colder. 37.5 Technology works with your body to adapt to its needs, keeping you in your ideal comfort zone longer.

37.5 particles absorb the infrared energy that your body naturally emits, powering the particles to either speed evaporation if you’re hot, or to help keep you warm if it’s cold. Because our temperature regulating fabrics are activated by an individual’s own infrared energy, even a cold sleeper and hot sleeper can be comfortable in the same bedding.

For example, testing at Inside Climate demonstrated a relative temperature-balancing effect of 5 – 19° F (or 3 – 12° C) when bedding products with 37.5 Technology were compared against standard bedding products. This means that you spend up to 88% longer in your ideal comfort zone when you sleep in a temperature regulating bedding system featuring 37.5 Technology.

The temperature regulating fabrics powered by 37.5 Technology have been proven in multiple studies to increase performance and keep you in your ideal comfort zone longer. Fabric property tests in a laboratory setting do not always correlate to human comfort. To test how fabrics interact with the temperature and humidity of human subjects and their relative comfort value, we test a broad range of apparel, footwear and bedding with and without 37.5 Technology.

The temperature regulating fabrics with 37.5 Technology have consistently outperformed alternatives in testing at the independent Munich-based institute Inside Climate. For example, denim with 37.5 Technology had a lower combined temperature/humidity value by up to 5.3°F compared to denim with a competing technology. And when you add more layers, you get more benefits. The clothing system was cooler by up to 12.5°F when 37.5 Technology was used in both the denim pants and briefs underneath.

The best fabric for temperature regulation can vary by environment and usage. 37.5 Technology is not only embedded in a wide variety of fabric constructions, but also insulations, foams, and laminates to provide tailored thermoregulation in apparel, footwear, bedding and more.

In independent consumer testing, users consistently prefer products with 37.5 Technology. For example, in one consumer test of insoles made with and without 37.5 Technology, 95% of users preferred the insole with 37.5 Technology for thermal management and 89% preferred the insole with 37.5 Technology for moisture management.

In a study done by scientists at the University of Colorado Boulder, thermoregulation clothing with 37.5 Technology was scientifically proven to increase athletic performance by up to 26% by reducing the increase of core temperature during activity.
