We bought one of these after getting caught in the rain once too often with nothing to carry rain gear in.  As it happens, this has turned into one of those "must bring" items that's perfect for nearly any trip.  It's vanishingly small when tucked into its own pocket and allows you to carry the inevitable accumulation of *stuff* when unfolded.  Great for day hikes, cross-country skiing, picnics, bike trips, conferences, beach binges, sailing, and nearly anything else. Even rain gear.  Sturdy stuff, quality workmanship and Hammock Bliss' customer service is tremendous.
