When paired with a shell jacket, it provides remarkable warmth, but its high air permeability lets a breeze easily cool you down, making it ideal for maintaining comfort as you warm up. Keep your Core layer on for effortless thermoregulation - just adjust your outer shell, for example the 49g Sonic windproof, to stay in control of your temperature.

This allows you to keep your Core layer on even when you have warmed up and you can thermoregulate by removing/unzipping your shell (eg. Sonic windproof at 49g).
