Kirsten R.wrote a review of SmartWool Midweight Zip Top - Boys' on November 5, 2010
We love the smartwool long underwear tops for adults and kids, zip top and crew neck.
They all seem to run almost a size smaller and are definitely snug. This is great for our skinny 11 yr old, but he is already needing size XL in tops and bottoms only in Smartwool brand.
The navy color is as expected--good for boys or girls. Warm, washable, very comfortable. I wish we owned 5!
