Crashtag is a California based company making what could be the most essential accessory for the cyclist: an ID tag with all your most important information in one convenient location. The tag is made of titanium, and is worn as a necklace. There are two sizes to choose from, one larger with a built in bottle opener, and a smaller model without the opener. One side has a graphic of your choice, the other side your personal information. There are several choices for the cord, from a simple string with magnetic closure to a more traditional ball chain. There is plenty of room on both size tags for the pertinent information needed in case of an emergency. The text is laser-etched, and the tags are made in the US. The Crashtag is a simple and reasonably priced product that could go a long way to help save your life.
