This bag will keep your Christmas Tree and Decorations safe and protected year after year. Made of the highest grade material this bag will not rip or tear. The 600 Denier, PVC backed waterproof Polyester is the strongest material available in a Christmas Tree bag. You will normally find this material is used to protect sails on yachts or to cover cars in the winter. The carry strap is sown right across the underside of the bag for additional strength when carrying heavy loads.
