A T-shirt featuring the beaver: the chief engineer of swamp ecosystems. By building dams, beavers slow down water runoff and raise water levels in the landscape. That helps keep peatlands wet, and a wet bog = less CO₂ released from decomposing peat. Pull on this T-shirt as a show of support for these exceptionally skilled builders.

Made from 100% certified organic cotton, it works just as well in everyday outfits as it does on walks through the forest or visits to the bog. The fitted, close-to-body cut keeps things comfortable day to day (women’s version: the shaped, slim fit cut). With no elastane, the fabric is fully natural and breathable, it moves and breathes with you, even when the ground gets soft and swampy.

 This T-shirt is made by KABAK – a Polish brand active since 2013, combining bold, conscious design with responsible materials and local production. Their mission is to make sustainable living easier: offering eco-minded design, sharing knowledge, and supporting initiatives that help protect the kind of world we all want to live in.
