What Our Gearhead(R) Experts Are Saying: "I use this as my go-to active insulator when I'm moving fast in cold conditions. It stretches really well, never feels restrictive, and the PrimaLoft Gold Active+ keeps me warm without overheating. It's especially good as a midlayer for technical days or as a standalone piece in dry weather."
