Christmas Plaid Footed Pajamas Finally, just in time for those awkward holidays-themed family photos, the entire clan can deck themselves out in seasonal, matching plaid this winter. Funny and well, true. Furthermore, the bulky, rigid packets of frozen PCM can cause additional discomfort, particularly if the user must wear a harness, safety belt or other close-fitting protective gear over the frozen PCM packets.

However, both chemicals have only one-half the latent heat of fusion of water ice , so the packets need to have twice the mass compared to ice , to have equivalent heat absorption capacity. Furthermore, the bulky, rigid packets of frozen PCM can cause additional discomfort, particularly if the user must wear a harness, safety belt or other close-fitting protective gear over the frozen PCM packets.
If the forced-air circulation is interrupted, the wearer can quickly overheat because of the impermeable nature of the garment. Furthermore, air-cooled garments are typically bulky to provide an air space near the body for circulation and therefore cannot be worn under close-fitting garments.
The wearer must remain tethered to the source of circulating air, making this type of system unacceptable for most mobile applications. This technology works exceptionally well under all types of outer clothing, providing both a continuous and consistent level of body cooling using a thin, lightweight garment with an integral network of microtubing through which chilled liquid circulates.
And this technology works well in environments where evaporative and phase change garments are ineffective or impractical. Detractors of circulating liquid cooling have stated that the user must remain tethered to a stationary source of chilled liquid, making this an inappropriate solution for mobile applications. Cooling duration is only limited by the amount of ice contained in the backpack or cooler typically enough for 4 hours or more and battery life typically 6 to 8 hours.
By simply replacing the ice and batteries when required which can be accomplished in minutes , there is no limitation on cooling duration. We are experts in liquid-cooled personal cooling systems. That's all we do. We do not offer evaporative, phase change or air-cooled products. We focus all our efforts on designing and producing the best, most affordable water-cooled personal cooling systems on the market. We have studied not only the personal cooling systems developed and used by NASA and the military, but also those offered by all of our known competitors.
While appearing to be a simple way to make a water-cooled garment, this product is lacking in several aspects:. This concept was first patented in and has been evaluated extensively by the US Military, who have overwhelmingly chosen tube over bladder construction for their personal cooling garments. Bladder-based construction has the following disadvantages compared to tube-construction garments:. The Veskimo Personal Microclimate Body Cooling Vest is made from lightweight breathable mesh fabric that will not inhibit the evaporation of perspiration, and has a thickness of less than one-quarter inch, so it fits easily under any close fitting garment or protective gear.
Its zippered front and adjustable-length elastic side straps make it easy to take on and off and adjust for best fit, comfort and the desired degree of tube-to-skin contact. Please see our How It Works page for more details about how we employ advanced cooling technology to create simple, reliable, truly effective personal cooling systems. Very disappointed in that. I ordered a Large because that's usually what I wear. This thing was a bit if a struggle to get on.
The main thing is that the thighs on this suit were made for somebody with chicken legs. I have a little more muscle in my calves and thighs and this thing struggled to slide on, even with generous amounts of lubricant. I should have just ordered an XL, but I fear that other parts would have been too big. Once the legs were on, I had to pull up as much as I could so that the inseam actually met my crotch so I could zip it up properly.
Once that was dealt with, the rest of the suit was fairly easy to put on. Fit ni ce and snug and overall I still enjoy it. Once it on it fits okay, but I'm scared to even sneeze because some parts of the suit are too tight.
The zipper goes from the front top of the neck, all the way down and around to the tailbone. Front entry, and allows rear access incase you don't want to take off the full suit. Design is decent quality. The seams are actually fairly strong. A lot better than I expected.
