I have pretty much given up getting hold of a decent gaberdine or Ventile(ish) cotton smock in olive green for less than £80.00. And I am now looking at copies. This one from the Bushcraft store seems reasonable. Does anyone have any experience of them. Apart from it not being cotton it looks pretty decent for the money.
