Developed over a period of almost 10 years, the Grit FLEX is the sixth generation of Hockey Tower bags. Improvements made to this bag include a padded shoulder strap which allows the bag to be comfortably carried, a composite frame which reduces the bag weight by almost four pounds and allows flexibility, better ventilation, improved shelving system for quicker air drying and high visibility lining. The bag also folds up instantly for storing beneath the bench during games.
