Baby Bogs boots are waterproof, warm and designed for everyday wear. Constructed with 3mm Neo-Tech waterproof insulation and DuraFresh natural bio-technology to fight odors. The plush lining gives both warmth and comfort and evaporates sweat to keep feet dry. These wellingtons are vegan friendly, machine washable and are comfort rated to 14°F/-10°C. The velcro strap makes for an easy fit but we would advise going up one size, as this product comes up short.
