  • Soft and true to soze
Size: Small Color: Red
Purchased these in red for my petite 10 year old daughter (she is usually a girls small/medium or size 7/8). The medium fit her great and the red is a true red. She loves them as pajamas now, but as the months get colder where we are, will be using them as a base layer when we play in the snow. She reported that they are cozy, soft and warm. We have washed them several times and they are still soft. ... show more

  • Great for the value
Size: Large Color: Black
Got these for my 7 year old. She's very tall for her age. She's a M waist with a L length, these fit a little loose which was perfect, I anticipate getting a full season out of them. They are a light, soft fleece on the inside and the stretchy athletic fabric on the outside. I already ordered another pair. ... show more

  • Cozy Comfort for Chilly Adventures
Size: Medium Color: White
I recently purchased the Thermajane Girls Thermal Underwear Set for my daughter, and it proved to be a winter wardrobe essential, providing both warmth and comfort during chilly days. Paired with her cat ears for a playful touch, this base layer set exceeded our expectations in terms of quality and functionality. The first thing that caught my attention was the ultra-soft feel of the material. The fabric is gentle against the skin, ensuring that my daughter remained comfortable throughout the day. The thermal design efficiently retained body heat, keeping her warm without adding bulk to her outfit. ... show more

  • Runs baggy and also runs short in the leg length
Size: Medium Color: Black
These are a nice quality thermal underwear and my daughter loves the soft lining. I selected tan small but really they tan short in the legs and were not form fitting. I ordered the girls medium. They were baggy and the legs were a little short. My daughter is just barely over 4ft tall and under 60lbs. While she loved them and they worked for what she needed, these will not get much use as she will out grow them and sizing up will be way too big. I would like these better if the legs were a little bit longer and the fit was more form fitting since these are suppose to be worn under clothing. ... show more

  • Great value, super soft
Size: X-Small Color: Pink
I have a very picky kid when it comes to clothing and comfort. We needed to start using a base layer, so decided to try ThermaJane based on recommendations from a mom group. My daughter is obsessed and asked me to buy more that she can use as pajamas! The inside is super soft against her skin, and also keeps her warm. She does have very sensitive skin, but we haven’t had any issues with this fabric! ... show more

  • Wow so soft
Size: X-Small Color: Black
These are thick and very cozy soft, hopefully they hold up throughout the winter season. I purchased for my daughter's Halloween costume, since temperature dropped in Massachusetts and she seemed to stay warm enough.

  • Warm lining
Size: Small Color: Navy
I like that it looks like dri-fit but inside it is lined and warm. I ordered a girls small 6-7 and it fits my rather small son just right. My son is average height (size 7 in carters) but thin. I read the girls come a little smaller so thats why i ordered it. It was fitted but not too tight.
