Very large
Ordered a 3T for my girl who is just out growing all her 2T clothes. This is huge on her!
thick but stiff
compared to the thinner terramar base layer, my kids prefer the terramar. They say this fabric is a bit stiffer. They say it keeps them just as warm though.
Good quality but HUGE
I bought a 3T for my 3 year old and they are huge on him. We went back and bought the 2T and they are much better, but still big. He is slim and these are not. The quality is very good and they do keep him warm.
Perfect for winter
Stretchy & soft medium weight with comfortable cut and great color. Perfect for average sized 3 yr old in size 3T. Loose enough that she can wear as a shirt, not just long underwear. We are in Alaska, temps 10s, great for in house wear & layering under her puffies. Ordered in both colors for her and her sister.
Highly recommend
Runs large. The 2T has room to grow for my 23 month old that is very tall. Great quality, comfy, soft, great color.
Good quality for a good price
High quality; solid price -- a great addition for a toddler in the Midwest!
Held up to weekly wear
Happy with this purchase several years ago that has held up to preschool wear multiple times a week for several years and all those washes! We air dry this shirt but it is superb and obviously very comfortable for our son to wear so frequently. It also doesn’t stain easily and breathes great, while being good for layering in the cold of Colorado, New Zealand or Seattle.
