You can’t sneak up on someone wearing the Spidey Sense Shirt. This shirt has a clip-on proximity sense with a vibrating motor. If someone comes within 5 feet of you it starts to pulse, at 4 feet the pulse quickens slightly, faster yet at 3 feet, then even faster at 2 and 1 feet away. Your Spidey Senses will really be tingling. This officially licensed Marvel collectible features Spider-man on the front. If you want to buy it, you’ll have to hold onto your Spidey cash until October- but you can preview it at this year’s Comic Con.
