REI offers its REI Men's Reversible Rib-Knit Beanie in Charcoal/Light Grey (pictured), Black/Charcoal, or Navy/Maroon for $4.83. Opt for in-store pickup to dodge the $5.99 shipping fee. That's $15 off list and tied with last week's mention as the lowest price we could find. It can be worn as a tall hat, as a snug beanie with the bottom edge rolled up, and reversed to the striped side in either of those styles.
