The Independent 11/15/08 Midweight Crew Base Layer

Coconut-based clothing brings to mind rustling skirts and comedy bras, hardly suitable for Britain’s bracing weather. However, Marmot’s warm and snug base layer uses 30 percent “upcycled” (waste) coconut husks that are carbonized, then blended with polyester. The result, Polartec Cocona, dries incredibly fast, offers full UV protection and feels very soft. The fabric also controls odour naturally so you won’t feel too smelly after a hike. And unlike some anti-microbial treatments for artificial fibres, this should last the full lifetime of the garment.
