'In your dreams!' they told you when you said you wanted to be a Starfleet officer. But with the Star Trek Science Spock Men's Pajama Set, you can finally show them that your dreams were actually quite logical. Designed to look just like the blue and black science uniform worn in The Original Series, you won't have to visit the Holodeck to transport yourself to life aboard the USS Enterprise. Made from 100% cotton, you now have permission to sleep freely.
