- Brand: mont-bell - Model Name: CHAMEECE Muffler - Color: Light Blue Size: 24 x 160 Ultra-fine microfibers, just one-tenth the thickness of a human hair, trap a large amount of air between the fibers, providing high heat retention despite the thinness. This is a new, unopened item, but it will be folded for shipping to make it thinner. Children's sizes are also available. How about matching sets? Thank you for looking.
