For a geeky day at the beach, make sure that you pack this Doctor Who TARDIS Beach Towel. The design is great and it looks just like the front door of the TARDIS. Instead of entering it, you will just be laying on it.
No beach-going geek should leave home without it. It is made of 100% cotton and measures 60 inches long by 29 inches wide. It is also an officially licensed Doctor Who product, so you can be sure that the BBC has approved it.
Of course any Timelord needs a cute companion. How can the ladies resist when they see this towel? Just $19.99 from Thinkgeek.
