Even arctic temperatures are no match for this innovative and versatile foot muff. Forget about layering on garment after garment—the Le Sac Igloo is our most popular one-and-done solution for getting little ones all bundled up for the cold. And though it's designed especially for bitter winters, it's convertible: the removable fleece insert reveals a cotton lining that works on its own during warmer months. It fastens easily to any stroller or car seat and the detachable cover converts into a single-panel blanket. Other smart features include an ergonomic hood with removable, vegan-friendly faux fur trim; an anti-slip back panel that keeps the foot muff in place on long walks; and a removable back panel for easy access to the safety harness, anytime you need it. The outer shell is water repellent, the microfleece lining is soft and cozy, and it's easy to keep clean. Just wash and dry!
