NWT Boys Adidas Track Bottoms Pants Size US Medium

I bought a few of these when I was in the UK as my boys lived in these style of pants and they washed so well. They are polyester with a soft mesh lining. Cuffed bottoms. Great for the Winter as made with reflective technology and have reflective strips on the back of the legs as shown in photo 5. Size US medium / UK 11 -12 yrs. Inside leg approx 28". Please note colour is between navy and grey and more true to photo 4.
