A cool pair ready for fun in the sun!
This is a 'sold seperately' type thing, but they do match & are made to go together by the same company. It's a "Boys Swim" set...and the shirt brings something new:
It is special fabric (or specially woven) to block out the sun as a 'sun screening tee' so you can have more fun in the sun. It is made of a sort of lycra-feeling stretchy but very smooth cloth. It has blue collar, red sleeves & navy front. The Sonic is CG in a 'caution' triangle with red lightening bolts & his name above. This is likely a dye-sublimated tee so it can't peel/go wrong.

The shorts are red on top, with jagged blue/navy lines going horizontally starting midway down. There's CG determined/ready Sonic on one leg (big good graphic) and the full color modern logo on the other leg. It has an elastic/draw-string combo for the waist. Each item should be about 12 dollars in 2020. (This SHOULD be a Spring item, but apparently it slipped out early so you can start asking about it at your Target store)
This is nice to see: something that's finally 'not another tee', but rather water-stuff with nice attention to design & good Sonic content. It's too bad it's not in larger sizes or for adults though...XL may fit a smaller teen so do check the section if they seem interesting.
