EDZ have developed a range which combines to create a versatile layering system for use over varying temperatures. The advantage of this system is it is not bulky and it allows the wearer to vary combinations to suit the conditions.
Hot conditions - All Season Base Layer
Mild Conditions - All Season Base Layer or Merino Base Layer + Innershell if required.
Cold Conditions - All Season Base Layer or Merino Base Layer  + Midlayer + Innershell if required.

OUTER LAYER - Leather or textile outer layers provide the first line of protection from the elements.
INNERSHELL - Windproof liner worn over base layer and midlayer to reduce cold air coming through outer layers.
MIDLAYER - Additional insulation layer worn over the base layer for extra warmth
BASE LAYER - Primary insulating layer worn next to the skin to trap heat from the body
