As anyone who has ever spent a winter in New Hampshire can attest, winters on the East Coast are cold as hell. Burton built the Men's AK NH Insulator Jacket to handle the bitter cold mid winter conditions of New England. It starts with a lightweight, yet tough ripstop fabric that offers some water resistance for when you're wearing the NH Insulator as an outer jacket when touring or heading down to the store. A heavy dose of Primaloft Silver insulation helps you stay toasty when temperatures plummet, yet it's still lightweight and packable so the jacket works as a midlayer you can stash in your pack. And when you're wearing it under a technical shell, the articulated AK fit allows you to still move comfortably. When winter brings its worst, be prepared with the NH Insulator.
