This arrived very promptly and as described. The seller is fine, but the manufacturer's description is a little misleading. It describes on many websites the 'Altec fabric', but try finding out what this is on the internet and you will be disappointed. Whatever it is, the label on the jacket reads `Main 100% Polyester, Other 100% Nylon, Lining 100% Polyester'. So no different to any other jacket at this price. It is fine for me, I needed a new jacket as my old Endura had lost its waterproof qualities and the Altura is slightly lighter. However, on my long hard ride to work this morning I arrived just as sweaty on the inside as any cycling jacket costing less than £100 would make you.
