Samsonite via eBay offers its High Sierra 36" Pack-N-Go Duffel Bag in several colors (Blue Velvet pictured) for $25 with free shipping. That's the lowest price we could find by $19, although we saw it for $15 less last month. It functions as a duffel and a backpack and features a zippered opening, toiletry pouch, and detachable shoulder strap.
