Here's what other sites are saying:
Great for sea kayaking, this bag lays flat on the deck for quick, easy access. Small and light bag is stuffed with 55' of high quality, 1/4" floating polypropylene rope. Rope is soft and pliable, making it easy to work with. Built-in floatation keeps bag afloat after it is tossed. High-tenacity pack-cloth bag protects rope from abrasion and UV-damage.
