Every golfer needs a lightweight top that can act as either a mid or top layer depending on weather conditions. The new Crail performance mid-layer does exactly this. It benefits from being made from a performance polyester/elastane mix which gives you all the movement that you could ever wish for. There is a brushed fleece inner that maintains the warmth and acts as thermal regulation. This allows the top to be wind resistant. The fabric is also Teflon coated which acts as a barrier to repel water.
