Made from 86% Nylon 14% Spandex the Softcore is the ultimate insulation base layer, perfect as a base layer or worn on their own. Available in both long and short sleeve, it boasts UPF 30 sun protection in a four way stretch fabric for fantastic fit. The fluffy brushed inner side offers warmth, wind protection, wicking properties and climate control in the softest most comfortable fitting thermal you will ever buy. The purposefully chosen fabric make up offers huge advantages over products like Merino as it dries much faster and the Spandex compression fit system can add safety and fatigue resistance by controlling muscle vibration and is thought to aid recovery between activity. The neck is pretty clever too, it’s nice and high like a rash vest, but with no front seam to avoid uncomfortable restriction around the front of your throat. They are machine washable and exceptionally quick drying. In the heat they work as rash vests and offer protection and in the cold they will keep you toasty.
