What’s so funny? Well, when you’re a dinosaur that ESCAPED extinction, you’d be laughing too! These jolly dinos love rocking out on the comfiest, coziest, most absurdly soft fleece pajama pants you’ve ever worn. It's even better than a trip to an island where you’re pretty sure the dinosaurs are extinct. Well - actually - maybe just get the pants and don’t go on that trip. They’ll feel like a vacation all by themselves (plus, no risk of attacks).

Fairly quick delivery, very cute!6

Nice PJ Bottoms for Winter

If you like the graphics, these are very nice PJ bottoms. When they arrived, they had no appreciable odor, which is good considering that many soft goods that I have received lately that originated in Asia smelled like bug spray. After washing these in warm water and drying on medium heat setting in the dryer, they came out with no pilling or adverse effects.The colors didn't fade in washing. They are very soft and comfortable, and the fleece provides plenty of insulating warmth, which is good because we keep our bedroom quite cool during the winter. They have an elastic waistband plus a tie string to keep them up. The only other thing to mention is that they don't have the traditional hole in the front with a flap or snap closure.

This size fits perfect on an average physique who wears 36 jeans, is 6ft and 200ish lb. Very comfortable right out of the package. Great lounge pants for your fave gamer or dinosaur fan.
