Compromising and economising on performance rainwear in winter is a big mistake, if you are an avid, twelve months of the year golfer who is serious about looking after the finer details, then the Abacus Swinley Rain Trousers deserves serious consideration, not just for golf but any outdoor activity where rain protection is needed. Abacus specialise in golf attire, especially waterproof and windproof garments. Abacus\'s 37.5 Technology improves the micro environment inside the garment to provide fabrics that evaporate moisture in the vapour stage before it becomes sweat. When your overheating 37.5 technology speeds up evaporation and cooling, when you\'re cold the particles return to warm the body once more. 40-60% humidity is created and the ideal comfort zone range is achieved. The active particles are derived from coconut shells and volcanic minerals. 37.5 Technology has been importantly approved as skin friendly and also hypoallergenic, whist being permanent and will never wash out whilst laundering.
