The proof
Is In The
Testing
Both lab testing and consumer product testing have shown that clothing powered by 37.5 Technology has an unmistakable ability to help your body regulate temperature and humidity.
- Wearing briefs and denim pants containing 37.5 Technology can cool the temperature next to your skin by up to 12.5°F, compared to the same garments without 37.5 Technology.
- Wearing a dress shirt and suit jacket containing 37.5 Technology can cool the temperature next to your skin by up to 16°F, compared to the same garments without 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.
FAQ
Clothing
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.
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.
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.
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. Proven to decrease the rate of core temperature buildup and keep you cool more effectively than wicking. Scientifically proven to increase stamina by reducing the amount of energy used to manage core temperature. Proven to increase efficiency so you use less energy to do the same amount of work.

Taking Apparel to New Heights
Have you ever been midway through a climb and wished you had an extra layer? Most of the time, there’s really not much you can do. But for two days in August of 2017, 150 climbers on Eldorado Canyon State Park’s iconic Bastille formation were in luck—they just had to climb a bit farther up Outer Space (5.10b/c) to the 37.5® Technology Cliffside Shop.
