The Boys Polar Wolf 3in 1 Jacket is designed to keep the Polar explorers of tomorrow snug & warm on icy-cold winter days. It focuses on durability & insulation, so with this jacket, the winter countryside is one big adventure playground. For the outer jacket, Jack Wolfskin used an extra robust version of our tried & tested Texapore weather protection fabric. & should your child get snagged up by the hood, the safety press studs will release instantly & the hood will detach from the jacket. The inner jacket of the Polar Wolf 3-in-1 is made from our extra warm Nanuk fleece. It is very thick, with a smooth exterior & a soft, brushed reverse side. The clever system zip allows the two jackets to be zipped apart in an instant, so your child can wear each one separately. Which means your little outdoor fan is properly kitted out throughout the year.
