Our Long Cushion Storage bag (previously called Extra Large) gives you an extra 23cm in length over our Large Storage Bag. It is water-resistant, mould resistant, UV protected and breathable. It will fit the seat cushions and back cushions from a large furniture set.It's made from heavy duty materials and comes with convenient carry handles for transportation.If it's not possible to store your storage bag indoors during the winter months, we recommend turning it upside-down (zip on the floor) to prevent any potential water ingress through the zip.
