A flexible mid layer can be one of the most useful pieces of kit in your expedition armoury. What you need is a mid-layer that can regulate your temperature, keeping you warm during periods of low activity but breathable enough to prevent you overheating as you ramp up the exercise.

Additional qualities like wind and water resistance will help widen a reliable mid-layer to a dependable, year-round layering option. Our range of mid-layers, constructed from carefully-selected smart-synthetic fabrics, are designed to do all this and more.
