A nice lady from the Forestry Commission gave me the 411 on a few British brands that are used in the field by mountain rescue and other outdoor services in Scotland. Some suitable for common usage, some heavy duty and expensive.
First up; Páramo.
Páramo Directional Clothing Systems was set up by the founder and owner of Nikwax, Nick Brown. The company's manufacturing processes are based around ethical partnerships with groups in Columbia and recently Vietnam and Thailand. Further reading. A slew of tech and fabrics are involved but basically it all comes down to water/windproofing via NikWax and wicking. Colors and shapes are no nonsense. Full line here.
