Eagle Creek Pack-It Specter Cube

Light Weight Pack-It
This excellent packing tool comes with a high price which is the only downside I can find to this product. Consider that the bag, zipper and all weighs the same or less than a greeting card. Since I travel exclusively with my luggage every ounce counts. For me, it holds the equivalent of four stuffed without closing, quart-sized zip-lock bags with a little room left for sticking in underwear. Since I'm new to the product I can't comment on durability, but I've yet to have an Eagle Creek product wear out in many years of traveling. I highly recommend this bag and am purchasing another one myself. I hope this helps you.
