The insulation in the NanoAir Vest is warm, stretchy and breathable.

Paramo Enduro Fleece £150

This mid layer has been designed to work with a specific outer. The Enduro is wind- and waterresistant, which reduces breathability and makes it less suited as a mid layer under most shells, but with the Enduro/Ventura Windproof it creates a totally waterproof system. Weight 436g
