Using our revolutionary Core fabric, constructed from PrimaLoft® ACTIVE, this is an incredibly soft and comfortable addition to your layering, perfect for sealing out cold air and keeping that hard earned warmth in. Great on cold runs and even better for a chilly overnight in your sleeping bag. Fast wicking and quick drying, the Core Neck warmer handles excess moisture with ease.

PrimaLoft® Active is built from a synthetic plume woven through a knitted mesh, offering the warmth of a fleece but with less than half the weight. With all the benefits of synthetic insulation, Core products work wet or dry with incredible wicking properties to ensure you won’t stay wet for long. Using the 75g/m2 weight of PrimaLoft® Active means 58% of the insulation is derived from recycled sources.
