Description

A knit with all the qualities of a classic 100% wool sweater: warmth, structure, and comfort – without the downsides of itching, shrinking, or complicated care.

Made with the revolutionary Seawool® yarn treatment, where 32 grams of post-consumer oyster shells are ground together with 3-4 discarded and post-consumer PET plastic bottles, creating a polymer which is spun into the yarn. This treatment increases the durability, temperature regulation and body-odour reducing properties of the garment - without compromising on look, touch or performance.

• Made of 60% BCI Cotton / 40% Recycled polyester (Seawool®)
• Knitted and sewn in China.
