They are made from PUL and feature three snaps in the back to adjust sizing around the neck. Sleeves have elastic so can be longer than your baby and still sit above their hand. 

They have a pocket on the front to catch extra mess and keep everything more contained, long sleeves to cover clothes in winter.
