Welcome to the forum. We have few guys here from NYC . What do you want your bag to do? Usually guys here are already well prepared with everyday carry such as multitools, folders, PSKs (personal survival kit), FAKs (first aid kits), flashlights, radios and whatever strikes you fancy. Some guys on this forum have key chains that would make McGuyver blush. For most of us Grab bag consist of more clothing, food and water. You have to figure out if grab bag is going to be used as your only and last resort or if it is going to be an addition to your everyday carry.
