Ventile IS the best grade of Egyptian cotton, very tightly woven and it ROCKS when made into a mountain parka. I have a Synergy Works Ventile Parka that I bought in 1977 and wore continuously until the late '80s, it is worn, but, STILL works although it is a bit tight as I am a bit "larger"than I used to be....time and the crabs and the sweethearting crib...as Dylan Thomas wrote....
NO high-tech parka I have had will compare in utility or versatility of temperature/conditions with this and I have had about every highend one available, I now will only wear eVent shells or a Ventile, if I could get another.
