Our warmest base layer bottom for those who feel the cold in a boot-friendly 3/4 cut. The Men's Heavyweight Grid Fleece 3/4 Bottom is crafted from our 280gm Signature Merino Blend fabric that melds the luxuriously soft on-skin properties of rayon from bamboo and the unrivalled odour resistance of merino wool. We’ve engineered the interior with a 3D grid texture for added micro-air-pocket warmth and an extra soft skin touch.
