Sunice Ladies Golf Ultra light jacket

This is described as a jacket but more s base layer for Irish weather. It is a USA size M, so I would say size 12.
It’s an unwanted gift from Ryder Cup.

Always have a high-tech thermal knit jacket handy. Ours is made with advanced SuperliteFX™ technology to achieve the highest degree of lightweight stretch comfort while ensuring thermoregulation, which keeps your body at the perfect temperature. Elena makes a smart, highly breathable performance layer on cool and windy days without making a sound! This ultralight jacket is also sun smart, thanks to UV 50+ protection. Full-zip front with chin guard. Contrast flatlock stitching makes a stylish, form-flattering statement.

Thermal – consistently keeps the body at a comfortable temperature.

Breathable – wicks moisture to keep you dry inside and out.

Wind Protection – uses fine yarns to trap air and block wind.
