The Men’s Lightweight Crew Base Layer is the first building block for comfort in mild to cool temps. Our lightweight 200gm Signature Merino Blend ensures superior breathability, temperature management and unrestricted movement with 4-way-stretch, while melding the luxuriously soft on-skin properties of rayon from bamboo and the unrivalled odour resistance of merino wool. A naturally better blend and our bestselling base layer for a reason.
