The Men&&';;s Featherweight Merino Bottom is a high-performance, high-output base layer. We&&';;ve partnered with NuyarnA(R) to create best-in-class breathability and performance in this new featherweight 125gm Signature Merino Blend that sees raw bamboo combined with twist-free, technically spun merino wool. This fabric is faster drying, more air resistant, more elastic and astonishingly durable, not to mention soft-on-skin, odourless and offers 4-way stretch, all while melding the luxuriously soft-on-skin properties of bamboo and the unrivalled odour resistance of merino wool.
