Exploration starts early with these hand-drawn, exclusive National Museum of Natural History Children's Pajamas. The snug-fit pair is produced at a small-batch, female-run factory in Peru using 100% Peruvian Pima Cotton. Hand-sourced and blended with longer staple threads, this durable Pima cotton is the softest and most luxurious on the market, and it is also naturally hypo-allergenic and chemical free to protect your little one's sensitive skin. The all-over print captures all the hallmarks of the Smithsonian National Museum of Natural History—like Henry the elephant, Mammal Hall, Butterfly Pavilion, the Garden Lounge and more.

Enhance the look with Dinosaur Slippers and/or Shark and Fish Slippers, both sold separately.

Customer Rating: 5 out of 5 Great pajamas, but 2 piece sets are really small

These pajamas are SO soft and the print is really unique! I ordered the two piece for my great nephew and a one-piece for my great niece; the onesie is a great size match but based on the SI rec description of "very snug fit," I ordered a 3T for my great nephew even though he is a 2T. They arrived today and the tag on the PJ's say, "We suggest sizing up +2 sizes for all two piece pajamas." Neither the catalog nor websites stated this…had I known I would have ordered at least a 4T as they really are quite small. Returning and ordering larger size. Otherwise, love both of these pajamas and can’t wait to see the kids in them!
