This Voksi Explorer footmuff transforms between a car seat footmuff and a stroller sleeping bag, fitting newborns up to 3y+ for year-round comfort. Natural down and wool fillings with a 100% cotton inner and a 100% nylon outer deliver warm, breathable insulation, while BIONIC-FINISH® ECO adds natural water repellency. OEKO-TEX® Standard 100, Class 1 certification confirms materials are free from harmful chemicals. Adjustable hood drawstring, side openings for extra ventilation, and a quick-release zipper allow fast access and temperature control, and the back section detaches to serve as a stroller liner or play mat. Anti-slip backing keeps the footmuff secure during outings, and crash-testing with BeSafe in the recommended rear-facing position supports safe use as a car seat cover; 2025 updates include an improved foot end and hood for a better stroller fit.
