F-Pack

An awesome accessory that students, professionals, cyclists, and falconers wear around their mid-section to maximize carry capacity on adventures or quests. Not to be confused with "Fanny Packs," the F-pack is more streamlined and not worn by overweight, white people from the Mid-Western United States.

"Please remove belts, shoes, and F-Packs before entering the security line"
