We got these for a Halloween costume and they were the perfect color! The pants and around the arms were a little snug on my guy, and the material wasn’t as soft as I was hoping but still a really solid product and kept him warm during trick or treating.

These pajamas are very comfortable, They kept me very warm in the mountains without a coat. They are perfect to wear under snow clothes. The color is nice as well. The material is thick enough to keep you warm, but not so thick as to make you sweat from just wearing it. I don’t think it will wear out easily. I really like these pajamas!

This thermal pajama is super warm and comfortable. It's perfect for winter season when nighttime is freezing cold but wearing these pajamas really gives warmth to the child's body. This PJ is extra lightweight and soft and wicks away the sweat and keeps you dry and feeling comfortable throughout the night.

Once again, Vaenait hits it out of the park. These pajamas are warm, soft and super durable. Will definitely be buying again.

This clothing item for boys is excellent for really cold weather. This is made by TINFL by Vaenait and is called "Thermal Underwear" or "Base Layer" to be worn under regular clothes. This is made of 94% polyester and 6% polyurethane, designed in Korea and made in Vietnam. It should be washed before wearing. This top and bottom unit should fit close to improve heat retention for the body. Also, this is NOT flame retardant, so should not be worn next to or close to open flames. The top has a round neckline and is a pullover with close fitting sleeves and cuffs at the wrists. The bottom has a crotch opening for ease of bathroom use, a wide waistband, and cuffs at the ankles. The fabric is soft brushed on the inside, and smooth on the outside. This is easy to wash and dry. This is great for wearing for camping, school, or bedtime during cold winter weather.

These pajamas are great for layering or sleeping in during the Winter. PLEASE take time to read over sizing. My son is 8.5, weighs 88 pounds and I ordered the Large and the top is so small. I didn't even bother trying them on. I should have ordered the XL, but my concern is that the pant length would have been really long. He has Duchenne Muscular Dystrophy, so he's extra husky and it's tricky to find him warm pajamas that work.

Ordered a size 6 and these are accurately sized. The fabric is light weight, sleek and super soft. The inner lining is a soft warm layer that does retain heat well. They are comfortable to wear according to my son and can be worn as pjs or a warm under layer in the winter. Good pricepoint and quality. Would recommend.
