This is a North Face Primaloft muffler. It uses Primaloft, a synthetic fiber also used in North Face Denali fleeces, military gear, and ECWCS Level 7. It provides the same warmth as down with less bulk and is also water-resistant. Since mufflers are often worn directly around the neck, they can be washed, making them very hygienic. The color is black, and the muffler is approximately 170 cm long. It's in excellent condition, having been used very little. Thank you.
