HEROBIKER Kids Ultra Soft Lined Thermal Underwear Boys Long Johns Top Bottom Set 2pcs Winter Skiing Warm

I saw a review that stated these are not fleece lined but product description shows it.. can anyone confirm the fleece lining in this product?

Can the small size fit 2 year old

Where can I find sizing chart? What are the ages/measurements of the garments?

How do you tell what the size range is for small?
