You are correct my friend, I have had mine for 33 years, and was given it, in 1991, by my old friend, Hamish Hamilton. I wrote about it in 'Climber & Hillwalker' in 1993 or 1994, against the advice of others, that it would damage my writing career. I have all the Buffalo gear, but the S6 shirt is the Bee's Knees You need to have faith, and wear it, as intended, next to your skin. I have seen an example that survived a bombing in NI, and another that survived a stove explosion. I have met the (SBS) guy, who wore it, with 2 pairs of Ron Hill Tracksters, at -37 . Buffalo gear has saved many, many lives. Hamish never wanted to make the stuff in the first place, but lots of mountaineers and adventurers owe him a debt. When you see them posing on Everest, they're wearing the stuff their sponsor supplied, not, necessarily, the gear that got them there. Buffalo is legendary It wasn't designed for the Special Forces, it was designed to go walking in Derbyshire, it just massively exceeded expectations. Hamish invented Pertex, developing it from a material that was used for typewriter ribbons, it works by capillary action. The fit is important, but also, (again), don't wear ANYTHING underneath it. They may be expensive, but they're fantastic value, and they come with a lifetime guarantee. The S6 is windproof to 40 MPH, but good luck standing up beyond that!
