Aramark offers its WearGuard Men's Packable Nylon Jacket in four colors (Royal Blue / Black pictured) for $14.99 plus $5 for shipping.That's $15 off, tied with our June mention, and the lowest total price we could find. It features a mesh back liner, elastic cuffs and waist, and folds into its own pocket. It comes in sizes S to XL, although not in all size/color combinations.

Want it in a larger size? It's available in XXL and 3XL for $10 more.
