Buffalo Systems Special 6 Shirt/Smock:
The Buffalo concept diverges from the traditional ‘layering’ clothing system that stipulates the requirement for a three-pronged attack, geared towards tackling sweating, insulation and waterproofing. The Buffalo Pile & Pertex system, (Double P/DP), is NOT waterproof, but is highly water resistant, wicking and breathable. It is designed to fit snugly and be worn next to the skin, i.e. with nothing underneath! Whilst this might sound a little crazy to some of you traditionalists, there is a well-backed up body of evidence that supports the use of this kind of attire in certain inclement conditions, and this concept has been copied and allegedly refined by some well-known brands.
I’ve recently purchased a brand new Special 6 after owning a second hand version that was around 20 years old, (estimated from pictures of the logo, the old style without the red/any text). Despite this apparent age, the smock looked brand new, with literally no flaws in the Pertex 6/Classic material whatsoever. The heavy-weight fleece/pile had suffered some age-related flattening of the pile but wasn’t too far off as lofty as it was when new, (compared against a brand new pair of the Special 6 trousers).
