The Sherwood Core 2.0 Carry Bag consists of 500D polyester which makes it light, great for transportation, and comfortable to carry. It utilizes a straight zipper opening while the internal structure is lined with a water-resistant material. Everything is supported with two nylon straps that circumference the entire bag giving added support. The ventilation grommets at each end help to increase airflow inside the bag for faster drying time of your equipment after use.
