Update 1/10/15: Per a note from a visitor, looks like Fros-T is no more.
If you’re looking for cool, lightweight daily-wear undershirts, check out my Thin Cool Undershirts article.
For more technical cooling shirts/vest, check out my Hi-Tech Cooling Shirts article for more options.
I guess today is the day of high-tech devices, so let’s take a look at a newer, lightweight athletic cooling shirt line that will keep you really cool in those hot situations.
Before we get into the product specifics, one application I thought these light weight “under” shirts might be good for was the law enforcement. I’m not sure if this type of product would get sanctioned by the governing body that oversees what is approved apparel for police or firefighters, but one complaint I constantly hear from police officers is how hot and wet their undershirts get while wearing kevlar body armor.
Since there is no airflow between the undershirt and kevlar vest, any shirt they wear stays wet and uncomfortable – and it appears to be a pretty common (and solutionless) complaint .
Anyway, if there are any folks in the law enforcement out there that are either willing to comment below or possibly try one of these undershirts out and write me back with your findings, I’d love to hear from you. Maybe I can try one out too and report back.
FROS-T Sports (site offline, •), a venture/start-up based in Florida, has created a light-weight, form fitting, 4-way stretch athletic shirt and bra line that contain integrated cooling polymer discs distributed on the chest and back. When activated, the technology in the polyvinyl alcohol synthetic discs are said to keep you 10 to 20 degrees cooler than the outside temperature.
Here’s an excerpt from the company’s website (site offline, •):
FROS-T Sports, Inc. manufacture’s today’s Premier Advance Cooling Technology on apparel for all Athletes, Industrial workers and individuals with Heat Related symptoms i.e.; MS
The product is intended to help prevent Dehydration and Heat Exhaustion. The shirt is designed to cool the body core temperature to allow muscle support for optimum strength, endurance while maximizing mobility and comfort.
- FROS-T Sports Performance Cooling Short Sleeve Shirt ($44.95, l)
- FROS-T Sports Performance Cooling Sleeveless Shirt ($44.95, l)
- FROS-T Sports Performance Cooling Bra ($34.95, l)
- Youth versions of the Sleeve and Sleeveless Shirts are also available ($34.95)
How Does the Technology Work?
Polyvinyl Alcohol is a state-of-the-art synthetic material known for its “water loving” properties combined with an innovative design that creates an ultra-absorbent, drip-free process. Made from a water soluble and biodegradable material, the hi-tech polymer retains water while remaining dry to the touch. When wet, the
PVAChill Gear Material becomes about 10 to 20 degrees cooler than the existing air temperature. This provides a cooling effect for the user. When the material is no longer cool, usually 30 to 120 minutes, simply re-wet and the Polyvinyl Alcohol will begin to cool again.
Update (5/10/11) – Check the comments below. I did hear back from the company COO and we just might have found a shirt that will work under kevlar.
