Arocore is a soft, comfortable and lightweight fabric with a super soft brushed inner. It is a great choice for hoodies, warm up tops and track tops. Arocore is simply too good to use only for exercise though. At 210gsm and with a buttery soft handle, Arocore is made with comfort in mind for everyday wear as well. Arocore is an amazing layering fabric, doing double duty as a fashion layer and for that extra insulation you need in cooler temperatures.
