Our Double Up Heavyweight Neck Gaiter combines the best of both our lightweight and heavyweight fabrics! The top half is crafted from our 200gm Signature Blend for enhanced breathability, while the bottom half employs our warmer grid fleece 280gm Signature Blend to keep your lower face and neck toasty. Both blends meld the luxuriously soft on-skin properties of rayon from bamboo and the unrivalled odour resistance of merino wool and retain our flexible 4-way stretch and thermoregulation.
