Over 200 days - it rocks
Can't say enough good things about the Chariot and ski conversion kit. My daughter loves it, and it really isn't that heavy if you love to ski for fitness anyway. We did some extra outfitting to make it really comfy in the cold - we use the fleece bunting bag from Chariot, added some puffy Primaloft layers, put a foam pad under her butt and feet, and on really cold days add a hot water bottle - she sleeps comfortably in any weather, and has never complained about any cold ever. The only low quality component is the skis themselves - cheap rossignol junk, but when they wear out (over 175 days or so), just replace them with some Junior skate skis, and it is better than new.
