Great breathable underwear
Size: Medium, Color: 5 Pack - Breathable Micro Mesh
These are the only underwear my son will wear. He's very sensitive about different textures but he really likes these. I have the women's version and they are also very breathable especially in hot weather. They fit true to size but are form fitting so depending on the child and where they fall in the size range if they're the last number in the range you may want to size up if they're not a very slim build
