American Eagle Outfitters offers its AEO Men's V-Neck Mountain Pass Sweater in five colors (Peacoat Navy pictured) for $15.98. Opt for in-store pickup to avoid the $7 shipping charge (although some sizes are available online only). That's $24 off list and the lowest price we could find. It's available in sizes XS to XL, although not in all color/size combinations.
