First Thoughts On The 37.5 Technology

The normal core temperature in my world (the United States) is considered to be 98.6 degrees Fahrenheit. In scientific and medical terms that’s an approximation and considered mid-range. In the rest of the metric and temperate Celcius world, that translates to 37.5 degrees. Technology is ever-evolving! I think we have something here that is quite noteworthy, and I feel is revolutionary if adopted whole heartedly.

Mind Blown!!

I have been wearing tech shirts and base layers for 30 plus years. For the past dozen years, I’ve been testing and reviewing gear. The “wicking” of sweat (spreading liquid sweat onto fabric) has been a driver to get that moisture away from the body all this time.

And now here comes the “mind blown” revelation as I was digging deeper into this technology. Comfort during performance comes not from removing that sweat, but from a balance between heat gain and heat loss. Let that sink in for a bit.

37.5 Technology is removing the sweat vapor before it turns into that liquid sweat which is the key to comfort and ultimately performance. In other words, it’s reducing humidity right next to the skin to maximize evaporative cooling. The 37.5 technology removes the vapor (before it turns to liquid), and keeps the core temperature lower or more stable. This in turn, improves the performance factor.

For the average athlete going out for a typical workout, I don’t really know if the 37.5 Technology will be noticeable or evident, right off the bat. When I go for a run, it’s me in nature with a focus to get a nice workout in. That said, a focused intense speed workout could certainly see the benefits having better “equipment.” In addition, if I’m competing in a triathlon race, going head to head with my buddy at the Nordic center, or want to step up my game in my local Peleton group ride, I can see the magic of adding this kind of apparel to my arsenal.

A Deep Dive Into The 37.5 Technology

Here is some data that comes from 37.5’s website:

“A study at CU Boulder recorded up to a 26% increase in athletic performance while wearing thermo-regulating clothing powered by 37.5^® Technology.”

I see the occasional call-out for volunteer participants at CU Boulder for various studies. I’ve actually been to their labs for an experiment to study foot strike and running form. Hence, I think they do take their research pretty serious. Think about it, it’s a serious claim to be able to go longer or harder by simple wearing clothing made with the 37.5 technology. That begs the question, what makes it so, and how can it be relevant in my world.

Here are some of the features:

• Natural Active Particles – Ultra-porous volcanic minerals and coconut-derived activated carbon are incorporated into all kinds of fabrics, insulations, foams, and laminate materials. They have a patented process for how they do that, but it somehow makes it in.
• Powered By The People – The human body naturally emits infrared energy which is then absorbed by the 37.5 Technology in the material. In turn, this energizes the active particles to speed evaporation and remove humidity next to the skin
• Miniature Pores And Increased Surface Area – There are billions of micro-pores in the 37.5 active particles. This increases the surface area of fibers and other materials to remove moisture at the vapor stage before you break a sweat. Let me repeat that, BEFORE you break a sweat. Wicking the sweat merely distributes moisture! 37.5 Technology removes it.

37.5 Technology In Action – Women’s Rossignol Poursuite Nordic

First of all, full disclaimer, my wife is the test subject for the 37.5 Technology. She is quite the runner, and has a solid 25 year running resume and races to show for it.

The Rossignol Poursuite Nordic is a stylish fitting piece of apparel ideally made for Nordic or cross country skiing. This is one of the more intense forms of exercise that you can think of. I do partake in XC skiing, and I can tell you that it is a serious high heart rate workout. You need to have power, skill, and endurance to traverse cold and varying snow conditions on these funny looking skinny skis.

However, running would also seem to suffice as a more intense form of exercise that doesn’t require much more than a pair of decent shoes and supporting apparel. It’s a lightweight and form-fitting jacket that allows for unrestricted range of motion. And of course, it regulates the temperature and sheds that sweat vapor quickly. Additionally, the coat has a wind proof and durable water-repellent finish that sheds a light snow and rain.

37.5 Technology can be found in many products. The following is a select list of uses that have this technology, and I assume that list will grow as word gets around.

• Active Apparel
• Workwear
• Lifestyle clothing
• Footwear
• Bedding and mattresses
• Home Goods

Final Thoughts On 37.5 Technology 

This 37.5 Technology is an exciting new way to help regulate the core body temperature. I can certainly see a need for it while actively out there running, skiing, or hiking. In addition, it can help with every day clothing as well as sleep comfort. The possibilities are endless, I think.

Anyway, from where I stand, I see the benefits of improved performance which I see as a great advantage for peak performance. I’d say, give it a shot yourself to see if there any noticeable differences.
