Would definitely recommend this product with the leggings as well, keeps my 6 year old warm whilst football training but doesn't not hinder him at all. If anything he doesn't realise he is wearing it underneath his football kit.
Very flexible for my boy with no irritation at all
and just to add: nice choice of colours.
Very soft material, warm and comfortable.
Great as long as you try it on first we needed an age 6 for our 4year old!
keeps my son nice and toasty!
size is very long and narrow
