In 2 short years, the Ranger has become the go to bag for pros and amateurs alike. We decided to add some amenities based on customer feedback. The bottom of the bag is now a molded plastic bottom going 4 inches up the bag on all sides. The included rainfly will cover the top and front of the bag but still allow for easy access of the main disc compartment. The H2O also comes with a fully integrated water bladder system that can hold up to 2 liters. We have added a sleeve in between the main pocket and top pocket for that disc that gets used a ton. Additionally, the putter pocket has been expanded ever so slightly so that two discs fit snugly, yet get in and out easily. Everything that could be added to the great Ranger has brought us this exceptional addition to the most complete bag lineup.
