Warmlite Shirt test Feb 25, 2011 <\/strong><\/p>\n

\u00a0Snow swirled around me as I began walking up a 3,000 ft Big Sur mountain. Snow is rare enough in Big Sur, but even less common was the type of shirt I was testing. <\/strong><\/p>\n

Its called a Vapor Barrier Shirt, no thicker than a dress shirt, from a clever firm called Warmlite<\/a>. While walking uphill starting about 500 feet above sea level (ASL), the air temperature could not have been warmer than 32 degrees F\u00a0 as snow landed on me.<\/strong> <\/p>\n

After about two hours, when a chilly breeze started and the snow stopped falling, I put a standard hooded sweatshirt over the Warmlite shirt. Amazingly, that was all I needed to keep warm – all day.<\/p>\n

Climbing the mountain, eventually I was sweating enough that perspiration ran off in tiny streams – more than mere drips. Oddly – my wrists were sweating.<\/p>\n

I was wet under the shirt, BUT I wasn’t getting cold !<\/strong> My body stayed warm all day<\/strong> even though the outside temperature was in the low 30’s (maybe even in the twenties) with only the Warmlite shirt and then later a normal sweatshirt with a hood over it. I learned a new concept: wet is different than cold. <\/strong><\/p>\n

You can be wet inside that shirt<\/strong> (not everyone’s cup of tea), but remain warm !<\/strong> Kind of amazing. (Later I learned the correct way to use it is to loosen the neck and cuff when you start to sweat – so the sweat doesn’t even get started<\/strong>.)<\/p>\n

But by far, the most amazing phenomena was that this thin jacket (dress shirt thinness actually) could keep me so warm.<\/p>\n

I did put on a down jacket for descent because going downhill, I wasn’t generating much internal heat. That day was spectacular for photography and unforgettable for the exciting new (to me) camping technology.<\/p>\n

Works at home too !<\/strong> Excited about how well that shirt worked in snow, I’ve since tried it at home when seeing how much energy I could save in winter. When I would first feel cold, I’d put the Warmlite shirt on and instantly (not 3 minutes later, but as soon as I zipped it up) would feel 10-15 degrees warmer !<\/strong><\/p>\n

That did it. The shirt now goes with me on every hike, bike, skiing, camping, boat or plane trip<\/strong> as an emergency item<\/strong> along with a the requisite Swiss army knife, matches, emergency mylar tent, straw, and dental floss. I packed it for my entry in the Race to Alaska.<\/p>\n

You can find the shirts at Warmlite<\/a> in New Hampshire, founded in 1955. Their whole camping line of equipment is designed by a former NASA engineer.<\/strong> Here’s an article explaining how it works.<\/a> and their NSFW\u00a0catalog<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
