Keeping warm on a cold winters day is essential if you want to produce your best on the course. The new Hamilton Thermal top from Oscar Jacobson is used as a base layer to keep you toasty on the course even in the depths of winter. It is made from 85% polyester/15% elastane so has the necessary stretch qualities to fit perfectly without causing you any restriction. The top has a roll neck that ensures that warmth is not lost in this area. It is lightweight and is ideal for a sweater or jacket on top.
