Making a sustainable fabric can be a challenge. It can't only be about sustainability, it must also be about creating great fabric. That's what seawool represents. The fundamental building blocks are discarded oyster shells and plastic bottles, two big sources of waste. These materials are combined to create truly special fabric. The feel is pure luxury - a dense 9.3 ounces with one of the softest hands we've felt. Intensely brushed on the top for added softness, richly colored in unique heather tones. It gets better - the unique combination of ingredients (mostly the oyster shell) yields odor resistance and thermal regulation without the addition of added treatments. It's a more responsible fabric that's equally great to wear.
