Best Selling Holiday Print - a collaboration with artist Riley Sheehey, this water color illustration brings Christmas and the Holidays to life, setting it apart from all other holiday pajama prints. This 100% Pima Cotton Two-Piece Pajama Set is all-natural, hypo-allergenic and gets softer with every wash. We believe that only the best should touch their skin. Sammy + Nat adheres to CPSC regulations for their pajamas. Therefore, they run small and have a snug fit. For every pair of PJs sold, Sammy + Nat donates a onesie to a child in critical need.
