Product InformationNamed after a town outside of Seattle, the Snohomish jacket is made with a 15-ounce wool, which is considered midweight lighter than the 24oz Mackinaw. Wool is naturally water-resistant and has the ability to keep you warm even when its wet. Its been used as insulation that protects against wet, cold, and wind for thousands of years. If youve always wanted to have a buffalo plaid hoodie that looks a little bit like the Mackinaw cruiser, this is the jacket for you. Men's Snohomish Reversible Jacket - Redblkbuf - Small
