So I was wandering around a thrift store yesterday and my eye caught a gridded fleece top. It was a light khaki color and on inspection, I found a Polartec tag, and a military clothing spec tag, LARGE REGULAR SHIRT MID WEIGHT COLD WEATHER (GEN III) PECKHAM, INC.. It was manufactured by ADS Tactical (http://www.adsinc.com/). It is a 1/2 zip pullover with thumb holes in the cuffs and weighs 13oz. I would rate the size as an average XL.
It looks like a Patagonia R1, less some style. So I surfed on these military tops. Yeah, they are Power Dry, as is R1, as is Cabela’s clone of this top for $65-$75. They offer a hoodie for about the same price.
I don’t know if it is an apples and apples comparison for fabric weight, but I found that REI has a Power Dry top for a mere $36.50! No weight is given, but my impression is that it is lighter stuff. http://www.rei.com/product/802277
I found mil-spec surplus and new for $20-$35. Watch the manufacturer as not all of them are actual Polartec.
My R1 clone was all of $5 :)
