I bought these in size XL for my 9 year old son who is already about 1.6m tall. that they are definitely long enough for him. They are so long that if they last, he can wear them for several years. We bought them with pants but the shirt is great with a sweater or sweatshirt. He wears pants every day at home because they are so comfortable and wearable. I bought two sets because he likes them so much. Each set costs less than $8. You can't beat such a great price!
