This is my daughter's first thermal suit and it seems very comfy.  It seems mostly true to size, but a bit on the small size.  If I were to order again, I would probably order a size up.  Otherwise I am very happy with it.

I bought two suits for my children.  Both say the suit keep them warm. The price is great compare to other retail stores in NYC plus no sales tax to NY.  The free delivery was quick, ordered on Thurs and got it on Tues.  The phone customer service is great.  I would order from the same site again.
