About this item

  • 【Our pick】As the basic thermal underwear for children in winter, we need to choose good fabrics, have strong functionality and fine tailoring.
  • 【Selected fabrics】For the toddler thermal suit, we have specially selected highly elastic double-sided soft fabric, which is skin-friendly, warm, sweat-wicking and breathable.
  • 【Design Features】The classic design features a round neckline for easy on and off and a soft fleece lining, making it perfect for both girls and boys.
  • 【Set Usage】Young children are not good at expressing hot and cold. In the cold winter, the thermal suit provides enough warmth. When there are activities indoors, the breathability of our fabrics will also play a big role.
  • 【Applicable scenarios】In the cold winter, this thermal underwear set is the best choice for going out, indoor and outdoor activities, giving as gifts, or as pajamas.

The shirt and pants fit, but sleeves were super long, like 6 inches past his wrist. The pants were also way too long.

My 15-month-old daughter is tall for her age, so I chose the medium (2T) size. It was slightly big on her arms and legs, but overall, it fit well. The thermal is soft, warm, and comfortable. In 30°F weather, she wore this thermal along with a fleece top and a puffer jacket, and she stayed cozy.

These are so extremely soft!! My 18 month old is a big boy, 37" and 30lbs and usually in a 3T-4T with some 5Ts fitting him as well. I ordered what I thought would be a size up but they fit him quite well now. These are slightly long on him, but fit great given his string bean shape. I would think they're closer to a 4T size than a 5T but they should work on him for a while still. He stays nice and warm while we take my older child to the bus stop every morning and his normally sensitive skin is doing great with these. Great quality and a good price too! Highly recommend!

My 4.5 year old is really tall for his age and typically wears a size 6 in shirts so that's what I ordered. Even ordering his normal size, the shirt definitely looks a little short. The pants are fine but the sizing is definitely off on the set so I recommend ordering at least two sizes up if you have the ability to do so.The set's material is super soft and warm, and my son really enjoys wearing them even if a little bit of his stomach shows when he lifts his arms. Overall, I would recommend buying but highly suggest ordering two sizes up.

My son consistently wears 3T pjs; he can fit in 4T but they are a bit loose on him. We ordered 3T in these are they were definitely on the small side- exposing a bit of torso and hitting slightly above the ankles. I did wash and dry them before use so I'm not sure if they shrunk. That being said, he really loves them even with the tight fit. He asks to wear them every night in this cold weather so they must be comfy. I would just suggest ordering 1-2 sizes up if you plan to get a full winter out of them. We have not layered them but they are thin enough that they would work well as a warm base layer too.

I got this thermal set for my 2 year old, ordered a size 2T. It fits her perfectly. The pants and arms lengths were spot on. She thinks its so comfortable I have a hard time convincing her to take it off. The material is a medium weight, stretchy, and wonderfully soft. Fantastic base layer for the price. Great for winter layering!

I ordered these thermals for my son for under his snow suit. The material is super soft and fits true to size. It washes well without issues. These honestly could be worn as pajamas too and they’d be very comfortable. If there were adult sizes I would order a pair for myself.
