Relaxed fit: This garment is slightly loose for enhanced comfort.Inspired by the mountain-ready Summit Series styles of the early 2000s, the 2000 Synthetic Puffer Jacket is a modern-day version you'll want to wear every day. Stuffed with light and lofty insulation and engineered with highly wind-resistant WindWall fabric, this lightweight jacket isn't just exceptionally warm - it stops biting winds from getting in and causing a chill. There are multiple pockets for stashing cold hands or essentials (your choice), while reflective details provide visibility in low light conditions.
