This is a big bag designed for stowing sails or other gear on deck and is made with Sunbrella Fabric which carries a 10 year warranty The bag measures approximately 18 x 36 inches with side and bottom handles to help with handling and securing the bag. The closure on the bag is a double drawstring and I have added a Sunbrella flap that closes the mouth of the bag to the elements when the drawstring is cinched down. As with all of my bags the fabric is cut with a hot knife to seal the edges and minimize unraveling. All seams are double sewn for security and durability.
