Cotton or cotton blend - even linen (!) - we have every shirt your little lad needs for posing, playing or layering.
We also have some super stretchy casual shirts made from cotton and pique fabrics - great for layering with a tee as a lightweight jacket.
Most of shirts now START as small as 12-18mths if you no longer want them in a onesie so check the sizes showing as available. We go as big as 16yrs but ALSO to matching daddy in S, M, L, XL and XXL.
