Measuring 18.5”L X 10”W X 14”H, the Boston Bag will get you through whether you are heading to the course, the gym, or on an overnight trip. The side pocket is large enough for your cell phone, wallet or keys. There are two larger additional pockets: one large enough for a change or two of clothes and the other will fit a pair of shoes and more. The shoe pocket is reinforced to protect against crushing.
