Designed to keep the Polar explorers of tomorrow snug and warm on icy-cold winter days, the Boys Polar Wolf 3-in-1 Jacket from Jack Wolfskin focuses on durability and insulation. The outer jacket is made of an extra robust version of Jack Wolfskins proven Texapore weather protection fabric. And should your child get snagged up by the hood, the safety press studs will release instantly and the hood will detach from the jacket. The inner jacket is made of extra warm Nanuk fleece. It is very thick, with a smooth exterior and 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.
