    Keep Your Cool This Summer with Techniche July 14, 2017 - Josh Tack writes for his Touring Gear and Tips blog every month.

    A couple years back, I wrote up some tips on how you can beat the summer heat during your bike tour. I still swear by those methods today, but if you’re looking for another advantage over the hot sun, consider the Evaporative Cooling Kewlshirt™ Tank Top from Techniche. Made from lightweight spandex and Hyperkewl™ fabric, all you need to do to get it ready for your ride is soak it in cold water and throw it on. The Hyperkewl™ material soaks in the cold water and slowly evaporates it, producing a cooling effect throughout your core. You’ll get the best results if you wear it against your skin, and there are no issues with throwing a jersey over it. Techniche claims you can get five to ten hours of cooling relief per soak. I didn’t quite see this happen on my test ride, but I’ll concede that these last few weeks have seen temperatures in the triple digits, and it’s a dry, Montana heat. If the vest does dry out on your ride, you can always soak it again at the next sign of water. With a retail of $55, it’s not an overly expensive solution to keeping cool. It’s also not specific to cycling. Use it on hikes, runs, or any other summer activities you partake in. It’s another great way to stay cool out there, because pretty much everywhere, it’s gonna be hot.

  • HyperKewl Tied to Performance #3 - Increased Power Output

    HyperKewl Tied to Performance #3 - Increased Power Output

    In physics, power is the rate of doing work. It is the amount of energy consumed per unit time (J/s).

    The recent study completed by the University of Hertfordshire found that athletes wearing our HyperKewl cooling vest had a higher mean power output. The study found that the mean power output was significantly greater when wearing our HyperKewl vest than without the vest by 7.99%.

    Wearing a HyperKewl cooling vest while exercising or working means that you have more energy for work or play. The idea of increased power output is a logical consequence of the HyperKewl vests ability to help manage your body temperature (see article HyperKewl Tied to Performance Improvement # 2). You can work or play longer and faster because your body is spending less energy trying to maintain its core body temperature, and can put more energy to its muscles.

    When winning matters, when productivity matters, having a HyperKewl cooling vest by TechNiche matters.

  • HyperKewl Tied to Performance Improvement #2 - The Impact on Body Temperature

    HyperKewl Tied to Performance Improvement #2 - The Impact on Body Temperature

    As a follow up to my previous article on the recent study by Hertfordshire University on the impact of wearing a HyperKewl cooling vest on athletic performance, I wanted to discuss one of the study’s findings as it relates to the impact of wearing a HyperKewl cooling vest on body temperature.

    Some of the ways your body regulates its temperature are through blood flow and the release of heat through your skin.  When you exercise, both your core temperature and skin temperature increase.  Your core can release heat through your skin, but once your skin reaches a certain temperature, the skin is unable to act as a facilitator for the release of heat from your core. 

    Your body also uses blood flow to help regulate body core temperature.  As you exercise, different parts of your body compete for the flow of blood for cooling and energy.  Two key concerns for us are your core body temperature and the power output of your muscles.  Each part (core and muscles) need the flow of blood to maintain optimal performance.  In the battle of blood flow priorities when exercising or competing, regulating your body temperature will win out over power output to the muscles, so the hotter you get, the less blood flow to your muscles, and the lower your power output.

    Wearing a HyperKewl evaporative cooling vest helps to lower your skin temperature.  This has been proven in several studies.  When the HyperKewl cooling vest keeps your skin temperature lower, you are able to release more heat from the core over a longer period of time.  Releasing heat through your skin because it stays cooler with the HyperKewl vest means that there is less competition for blood flow between your core and muscles.  As a result, your muscles get more blood flow for longer allowing you to generate a greater power output for longer.  Hence, your performance improvement.  You can push yourself harder, for longer with a cooling vest because the HyperKewl cooling vest allows your body to naturally cool itself.  As I like to say, HyperKewl helps to supercharge your body’s natural cooling system.

    During the 40 km time trial used by the study, the temperature of several parts of the body were measured.  The mean body temperature was found to be significantly lower when the HyperKewl evaporative cooling vest was used (36.13C vs 37.14C). 

    During the 40 km time trial study, the relative performance improvement was 5.56%.  Time trials went from 74:16 mins without a HyperKewl cooling vest to 70:05 mins with a HyperKewl cooling vest.

    One of the key conclusions of the study was that cooling during exercise in the heat will reduce thermal strain and the rate of perceived exertion.

    Please keep in my that I am trying to summarize my understanding of the report and that I would be happy to answer questions, but the research team at the University of Hertfordshire are the experts on the results.

  • The Cooling Capacity of HyperKewl PLUS

    The Cooling Capacity of HyperKewl PLUS

    We recently completed testing with SGS on the cooling capacity of our HyperKewl fabric. The results were better than expected. HyperKewl PLUS fabric, when quilted as the middle layer between a waterproof nylon and a breathable outer nylon, generates an average 0.231 W/cm2. In terms of the cooling capacity of a standard vest (6529), that equates to up to 2287 BTU/hr of cooling from HyperKewl PLUS. Considering that a small air conditioner generates up to 6000 BTU/hr, the capacity of HyperKewl PLUS to cool you down is very impressive.

  • New Research Ties HyperKewl to Athletic Performance Improvement

    New Research Ties HyperKewl to Athletic Performance Improvement

    A recent study completed by the University of Hertfordshire demonstrated that using a HyperKewl cooling vest can help improve athletic performance.  We know that TechNiche Cooling products improve user comfort when working or playing in hot conditions.  We know that TechNiche cooling products improve worker safety by helping to reduce the risk of heat stress.  Now we know that TechNiche cooling vests can help to improve the performance of athletes.  Our motto “PERFORMANCE. SAFETY. COMFORT.” is now not only proven in the field, but is also proven in the lab. The testing was conducted around a 40km Time Trial in a hot environment. As we continue to dig into these most recent findings we will get you more details.  STAY TUNED!! We would like to thank Joseph Procter and the team at the University of Hertfordshire for their efforts in this research.




    Heat Stress ‘Dramatically’ Reduces Productivity, Study Finds BY LAURENCE STEVENS | APRIL 11, 2017

    Research into the effects of heat stress on sugarcane workers in Kompong Cham province found that productivity was dramatically reduced as daytime temperatures soared, a troubling finding given Cambodia’s lagging labor efficiency and expected warming over the next 30 years due to climate change.

    The study, based on research conducted in early 2015, found that the number of sugarcane bundles individual workers collected each day fell by 42 percent when temperatures rose by 2 degrees Celsius—down from about 35 bundles per day at 29.9 C to 20 bundles at 31.1 C—largely due to fatigue and heat exhaustion.

    Kongkea Phan, dean of the science and technology faculty at Phnom Penh International University who worked on the project, warned that by 2050, the agricultural sector could incur major productivity losses due to climate change-related warming. “The findings relate to all agricultural workers,” he said. “We want to develop guidelines with the government to help workers.” Moeun Tola, head of the labor rights group Central, said that although there were no specific health guidelines for heat stress, Cambodian Labor Law compels companies to provide a safe environment for workers.

    Neither the health nor labor ministries could be reached for comment on the study, which is currently undergoing peer review. (

  • With Summer Approaching, Heat Stress Concerns Grow - A recent report by HealthDay Suggests things will only get worse

    With Summer Approaching, Heat Stress Concerns Grow - A recent report by HealthDay Suggests things will only get worse

    The below article helps to emphasize the growing concerns about heat stress as average temperatures continue to rise across the globe. As we continue to work and play in these rising temperatures, we will need solutions that help us to manage the impact of the heat on our bodies.

    By Dennis Thompson HealthDay Reporter

    _MONDAY, March 27, 2017 (HealthDay News) – Deaths related to extreme heat are expected to keep rising, even if most nations can contain global warming at agreed-upon levels, a new study reports. Nations supporting the 2015 Paris Agreement have pledged to limit global warming to below 2 degrees Celsius (3.6 degrees Fahrenheit) above preindustrial levels. However, extreme heat events are expected to occur ever more often as the 2 degree Celsius limit is approached, researchers said. An analysis of 44 of the 101 most populous “megacities” showed that the number of cities experiencing heat stress doubled with 1.5 degrees Celsius (2.7 F) of warming, researchers reported. That trend would potentially expose more than 350 million additional people to heat stress by 2050, if population continues to grow as expected, the study authors said.

    “As the climate warms, the number and intensity of heat waves increases,” said lead researcher Tom Matthews. He’s an applied climatologist at Liverpool John Moores University in the United Kingdom. “Research has shown this to be the case for the global warming experienced to date, and our research is the latest to show that we can expect even larger increases as the climate continues to warm,” Matthews said. Even if global warming is halted at Paris goals, the megacities of Karachi (Pakistan) and Kolkata (India) could face annual conditions similar to the deadly heat waves that gripped those regions in 2015.

    During the 2015 heat waves in those areas, about 1,200 people died in Pakistan and more than 2,000 died in India. These heat waves are particularly threatening to large cities containing lots of heat-absorbing asphalt and concrete, not to mention huge populations, said Dr. Georges Benjamin. He’s executive director of the American Public Health Association. “Most U.S. cities have put in place response plans to address heat waves,” Benjamin explained. “That said, we still have an unacceptable number of premature deaths related to heat waves.”

    To examine the impact of global warming on human heat stress, the researchers used climate models and looked at how global temperature change could affect heat stress projections in the world’s largest cities. The investigators concluded that it’s likely there will be more land surface area exposed to dangerous heat stress. They also noted that areas already experiencing heat stress will have more frequent and longer heat waves.

    The United States will not be immune to this global phenomenon, Matthews warned. “Our research does not explicitly focus on [the United States], but in general, if the climate continues to warm, North America should expect more frequent and intense heat waves,” Matthews said. “More fatalities could be expected, too,” he added. In 2015, 45 Americans died from extreme heat, according to the U.S. National Weather Service. Overall, more than 9,000 Americans have died from heat-related causes since 1979, according to the U.S. Environmental Protection Agency. The National Weather Service defines “dangerous” heat as a heat index of about 105 degrees Fahrenheit, said Jennifer Li, senior director of environmental health and disability with the National Association of County and City Health Officials.

    Protecting people from heat waves will involve precautions that range from infrastructure down to community aid, Li and Benjamin said. “Preparing for extreme heat waves includes reviewing building design and refurbishing existing buildings to increase energy efficiency and decrease internal temperatures,” Li said. “Adapting to extreme heat waves can include updating and modernizing the electrical grid to ensure it is prepared to withstand peak demand during more frequent, more intense and longer-lasting heat waves,” she said.

    Large cities should establish plans for “cooling centers” to which people can flee on the hottest days, much like heating centers that are provided during frigid conditions, Benjamin said. City health officials can also distribute fans to people who don’t have air conditioning, and issue reminders in the spring for people to have their cooling systems serviced, he added. Internationally, officials should take these results as a further sign that global warming needs to be confronted through resolute action, Li added.

    “This study reveals that the global warming limits set by the Paris Climate Agreement should not be considered a safe amount of global warming,” Li said. “Further, interventions should be prioritized to slow the rate of global warming while at the same time increasing preparedness, mitigation, and adaptation efforts. Populations will be disproportionately impacted and vulnerable populations may be unprepared to manage the risks of extreme heat,” she added. The new study was published online March 27 in the Proceedings of the National Academy of Sciences.
