These toddler long johns are great! The fabric is soft, warm, and comfortable, making them perfect for colder weather. They fit well, allowing my little one to move around easily without feeling too tight or bulky. The material also holds up well after multiple washes without losing its shape. Overall, a great buy for keeping toddlers cozy in the winter!

If you live in a country like Canada, these are just to ensure your kids are warm when they go out. I usually make sure this is the first layer both top and bottom and then later up on top for best protection from the cold. Playschool outdoor activities are not stressful anymore thanks to this! The fabric is soft and Durable. I’ve bought multiple of these for my toddler !!

The pajamas are not just fleece lined but actually fleece exterior and a cheap material. so the item description is inaccurate. way too warm to sleep in unless you’re sleeping outdoors in the winter or camping. They do mot offer free returns and ask you to pay more to return than what the pajamas actually cost so not worth it. Seller’s policy is unfair. Save your money I’d suggest buying elsewhere

I bought these for my son who was going on a school trip this winter. The weather said it was going to feel like -22 with the windchill. He wore these under his clothes and he never complained once about being cold, even tho many of his other classmates did. He also said they were very comfy and he’s very particular about the clothes he wears.
