These are some of the most comfortable Kids long underwear you will find. First and most importantly, the 100% brushed cotton is some of the softest I have ever felt. I only wish my clothes were as soft as these OshKosh B'gosh long underwear. The next thing to look for is the cuffs, the cuff on these long johns are both very soft and stretchy so they won't get out of shape after two washes.
Let us not forget that we want our kids to look cute. Fortunately the OshKosh long underwear are adorable. The pair we have is a white base with pink and red snowflakes... very cute.
Since these long underwear are made from 100% cotton and not fire resistant, they are not recommended as pajamas. That said they are more than comfortable enough to be used as such.
It should also be noted that as this long underwear is not made form polypropylene or other high tech fabrics, they are not made to wick moisture away and perform like the stuff an adult might buy at a sporting goods store. That said cotton is a wonderful base layer on a cold day that will keep kids warm and comfortable.
The OshKosh B'gosh long underwear seem to run true to size making them any easy purchase. I won't hesitate to buy a new pair next year.
