I have two ventile garments both over ten years old and looking a bit worn, I have altered and adapted both to suit my requirements over the years, and now I have a good idea of exactly what my ideal ventile smock would be like, so I am in the process of making myself a new ventile smock (project for the new year).
This is the cheapest way to get a decent ventile - buy seconds grade ventile (usually very minor flaws), buy a metre extra to allow for this. My pattern is an very battered old arctic windproof, the cut of this is very good for freedom of movement, but the hood design needs to be adapted (better visor, more adjustment), I prefer flat-sewn pockets to the ones on the original. The zip, buttons, drawcords, etc, all will be stripped off the arctic smock.
It will be a single layer garment (dries quicker and does'nt get so warm) though the hood and shoulders will be double. Inside a dozen buttons will accomadate a goretex liner (very quiet to use and the ventile protects the delicate membrane).
Total cost so far - ventile £56 - smock for pattern £7.50 - thread £5 - velcro £3 - goretex liner £12.
Now all I need is the time to make it and I should have a good system for less than £85!!
West Winds are very good but the service is bloody slow.
