Cuddl DudsGirls Cold Weather Fleece-Lined Thermal Underwear 2-Piece Set - Kids Long Sleeve Top and Leggings Long Johns

These are perfect, lightweight but very warm, fit well under clothing, great quality and versatile.

Daughter found the pants very comfortable but the top too tight. She is slim but perhaps she is at the end of wearing any child's sizes.

I got a medium for my 6 year old daughter. She’s average height, and weights about 48 lbs. It fitted a bit lose and long but I think she will grow into it soon. She loved how it fitted on her and the holes for her thumbs. Most likely I will be getting at least another pair, but probably one size smaller, which is the small.

Loved it..

I bought this set for my 9 year old daughter as a base layer for under her soccer uniform. It fits well and the fabric is soft. It washes well and has kept her warm during chilly games and practices.

Daughter is 7, skis in Colorado weekly. Wore them Thanksgiving day for opening ski day and then wanted to wear them to bed and the next day. Had to convince her to wash them! Petite height, weighs 48lbs, I bought a 7/8 medium. I would go no smalller as there is room to grow, but they still fit close to the body as expected for under snow pants. Stretchy material. Comfortable. Fleece lined, smooth outside, thin not bulky.

I bought them for my granddaughter. The color and fit was perfect. It has been really cold lately and they have been able to keep her warm.. Only wish more colors were available.Excellent buy....an oh yes, great buy for camping because at night it gets COLD at least where we go.I recommend these because of the quality and price.

The right arm sleeve was stitched on in a twisted manner, thumb hole is on the pinky. Cannot be worn comfortably. Since this was a gift that was bought and wrapped in advance, was unable to get a replacement in the return window.If the seller is willing to send a proper replacement, I will update my review to 5 stars—I understand stitching mistakes sometimes happen during manufacturing, and we love everything else about the color, material and thermal ability. This one happened to slip by quality control unnoticed.
