Both footmuffs come with protective features like reflective elements, a built-in shoe shield, water-repellent materials on the outside, and breathable fleece lining on the inside. They also feature a two-way zipper, which lets you quickly adjust the top cover in different weather conditions, or turn them into a seat liner. The Bugaboo footmuff can be used year-round and provides optimal comfort from autumn throughout the milder winter seasons. It also folds into a compact package to store in your underseat basket. The Bugaboo THERMOLITE® performance footmuff is specially designed to provide comfort on even the coldest and wettest of days. It features an innovative THERMOLITE® insulation insert that keeps your baby warm and dry even in freezing temperatures (up to -20°C). The insert can also be removed and adjusted to fit warmer days. The material is a more responsible, cruelty-free alternative to traditional duck down. Designed with long-lasting heat protection, the filling is made from 100% recycled textile waste and PET bottles, and is certified by the Global Recycling Standard (GRS).
