This Ice cube M cooler bag from the "St Barth" collection is lined with thermal insulation to ensure perfect preservation of your meals and drinks, both hot and cold. This bag is only insulated, not waterproof. Any liquid spilled inside can seep through the seams and stain the bag. Our cooler bag is a transport bag; their large capacity does not allow them to support weight without risking pulling on the seams and damaging it. We offer the Ice cube range in 2 sizes: S or M. All our products are 100% made in France. Cut, assembled, and handcrafted by our seamstresses in our workshop in Bourg sur Gironde, near Bordeaux. Therefore, there may be a slight size discrepancy in the dimensions given as an indication. Composition: Outer fabric: 100% cotton / Thermo-reflective insulation: 81% PE, 19% PET / Strap: 100% cotton / Zipper pull: Faux leather
