Best long underwear for my toddler
Perfect long underwear for my toddler. I have a 2.5 yo and it will definitely fit all season long. He has already worn them multiple times under sweatpants as we live in a colder climate. Definitely already got our money worth and still have all snow season left. Will be able to wear under snow pants if its a mild day in the snow or with a pair of sweatpants between as it gets into the single digits and we still go out and play. Great quality!
Very popular.
Everything I needed out of $6 baselayer pants. Durable, quick dry, and apparently comfortable, since my 4 year old wore them for basically a week straight. I would say I saw AT LEAST 5 other kids wearing the same outfit on our trip. Only thing is, the butt area was HUGE. It easily could have fit a cloth diaper, which would be perfect in the smaller sizes, but many kids in 3T and 4T are in underwear
Great for cold weather
These fit my toddler so well. and they did so good at keeping him warm when we took him out to the snow. kept him warm but didn't over heat.
Perfect baselayer
Perfect baselayer for my child. Lightweight but seems warm enough for the chilly days ahead.
