A weatherproof mid layer jacket - wear as is, or under a sailing jacket.
Optimized for sailing, but also functional in other leisure time, the Lifaloft Hooded is a valid choice. In Helly Hansen’s scale, it’s a mid-layer jacket, but thanks to its weather resistance, it also works as an outer layer in many situations.
Helly Tech Performance: waterproof, windproof, breathable
The technical LifaLoft insulation wadding also tolerates moisture
The hood can be stowed away when it is not needed
