Mention was made (in another thread section) of SASS's olive green version of the SAS smock made in ventile cotton material. Ventile has always been a relatively expensive material and manufacturers of ventile outdoor clothing are few and far between. So, why not make your own ventile clothing yourself? Pointnorth Ltd (http://www.profabrics.co.uk) sell a range of first and also seconds quality ventile material from the bolt. The colour range includes olive green, navy blue, orange and loomstate (a sort of buff sand). With a simple paper clothing pattern from your local material shop and suitable quantity of ventile material as recommended on the pattern, I managed to produce a great windproof pullon smock with hood and pockets using a pair of scissors and a borrowed domestic sewing machine; all at a fraction of the price you would pay for a commercially bought one. I had an hour's sewing machine instruction from my girlfriend and then it really is a matter of a few hours of concentration and plenty of patience. Give it a go! As a result I now make almost all my own outdoor clothing, including Goretex waterproofs.
