This is the ultimate tool bag by Carhartt. With 27 total pockets there is room to carry all of your gear. Seventeen pockets are on the outside of the bag and ten are inside. The bag opens wide for easy access to your gear and the reinforced corners help protect your bag in harsh work conditions. The outside of the bag has a 1200 and 600 denier water-resistant membrane for those moist conditions. The padded non-slip shoulder strap makes carrying this bag much more comfortable!
