I recently purchased my kids this thermal set, and I couldn’t be happier with the quality and performance. The fabric is soft, stretchy, and super comfortable—perfect for keeping little ones warm during chilly weather. It provides excellent insulation without feeling bulky, so my child can move around freely, whether playing outside or wearing it under winter clothes.What impressed me most is how well it retains heat while remaining breathable. Even after a full day of outdoor fun, my child stays cozy without overheating. The fit is true to size, and the material is durable enough to handle multiple washes without losing its shape or softness.Overall, this thermal set is a must-have for winter! It’s practical, well-made, and ensures kids stay warm and comfortable all day long. Highly recommend for any parent looking to keep their little ones snug during the colder months!

Wow this product is soft! Very warm and well written description to match the product. The black is versatile. The fit is nice and has stretch. I see a few winters used out of this. Worth the money and the weight is incredible light.

My daughter worn this under her Halloween costume dress while trick or treating in 30 degree temperature.Material feels nice, fit her perfectly, kept her warm and comfortable(no complaints). Layered this under her dress costume and she worn sweat pants and a light jacket and was happy as can be.Definitely worth the purchase since colder days are ahead and my daughter will want to be out in the snow this winter season!

I ordered the light blue set for my son for our Colorado vacation. He loved how soft and comfortable they were. The legs were a little long but that’s common for this size for my son. There were his base layer for our snow activities and he never complained about being cold. Recommend!
