Fits well I’m a medium for tee shirts but large in this gives some room to swing.

Comfort is excellent. Fit is perfect all round the jumper

Perfect lightweight jacket for spring and autumn golf. Despite being very thin the fabric is fleece backed and adds just enough warmth to prevent you getting cold but without the danger of overheating should the sun come out. Sizing seems normal, I’m usually between medium and large - 5’10” with 42” chest, I opted for large and it works well for me as I often struggle with medium tops being too tight across the shoulders to swing freely. Length is possibly a touch longer than I’d like in a large but looks fine. I think I could have gone for either medium or large so if you have similar dimensions I’d recommend going with medium for a regular fit and large if you prefer something slightly looser.
