Overall the best overall's
Since I finished full time work I have to supply my own workwear and I have found the best workwear at the price are Dickies.
High performance waterproof clothing is designed to cope with energetic outdoor activities, pursuits and pastimes. Dickies manufacture products including waterproof trousers, coveralls, rain jackets and winter coats to provide a great range of products for your specific requirements. Additionally there is a range of Dickies wax clothing, which will also have water resistant properties, and are very popular for use in the UK countryside.
The majority of Dickies wet weather coats designed to be lightweight and packed away when required. The Dickies Vermont Rainsuit is a classic example of the type of product. With these being lightweight jackets it can be advantageous to purchase a warm fleece jacket or sweatshirt to wear in addition for layering. Or, if bulk is not an issue, you could go for the full tunnel suit (Dickies Waterproof Padded Overall). This will provide warmth and full body coverage in addition to wet weather protection.
We also have a great blog post on the history of waterproof clothing. Feel free to pop across and take a read to discover how your rainwear has evolved over the years...
