If you find yourself traveling with any sort of regularity, then you no doubt find packing and unpacking something of a chore. The Lay-N-Go Traveler is a clever little bag that is designed to allow you to quickly pack and unpack your essentials and/or personal effects.
When open, it becomes a flat mat (no more fishing through toothpasty toiletry bags). Tightening the drawstring pulls it into carrying mode.
Personally, I swear by (and will stick with) my somewhat less classy and slightly less convenient solution of putting all of that kind of stuff into ziplock gallon bags, but if I traveled a little more often then I might be persuaded.
