City ThreadsProduct image Made in USA Big Boys Thermal Underwear Set Perfect for Sensitive Skin SPD Sensory Friendly Base

My 9 month old son loves these! He's a bigger boy so we ordered size 12 month which is what he normally wears in clothing and they fit perfect! Great quality and super cute too!

For size reference, bought a 3T for my almost-5yo - he’s 4 but will be 5 in about a month, and he’s on the smaller side of 4. Idk his particular measurements but basically he normally wears a 4T/4 top (not snug) and 3T/36 mos. bottoms. The size 3T set fit our son perfectly - definitely not even a little loose like on the 3 modeling boys in the Product Description picture, but much more snug, which is what we wanted as a base layer. The sleeves are a bit short for our boy since he normally wears a size 4 top, but the waistband and length of the bottoms were perfect.These were fantastic for a vacation in cold weather, worn as a base layer. I worried they would be too thick/and or too itchy to wear underneath other clothes but they’re not thick at all - quite thin actually yet surprisingly very warm! It’s some kind of really tight weave so it keeps the warmth in vs. having tiny little stitching holes everywhere like I was envisioning with a “waffle weave.” And super soft and comfy at the same time! I really liked that they were thin enough to take up very little space for packing as we were trying to travel light. We ordered 2 sets of these (both in 3T). My sone wore one or the other every day during our 9-day vaca in 30-45 F weather. I’m thrilled that they worked out.

My son is 3 years old and on the small side. He weighs 27 lbs and is 36 inches. Typically a 2T fits him perfectly and 3T gives him room to grow. I purchased these thermals in 3T and the top fits him perfectly and pants do as well but they are a bit long. I do love that it is soft, color is as depicted, and overall good quality. Not only are these good for undershirts, my son loves wearing these as "japanas" (pajamas). I will be purchasing another in 4T. If it was cheaper than $23.95, I'd purchase a lot more colors.

City Threads thermal was the best brand than others I used even name brands like GAP to Ralph Lauren. Fit as expected but bought a 4T for my 3 year old. The reason for a size up is because naturally fabric shrink after washing and drying multiple of times. The Thermal fabric did not shrink much and the 4T fits well enough without being snug fitting nor short on legs and arms. Keeps my little one noticeably cozy during the harse New England winters. City Threads is a winner for us and worth the price. So far I bought this brand in two winters 2016/2017, and color options are a very nice touch. Also, great as PJ’s or get kiddo half dressed the night before and ready half the time in the morning before pre-school and work. Overall, great buy in my opinion and life saver for this mama. I believe it is made in the USA if that matters to you.

True to size. It will not shrink after you wash and dry it. It holds up great. I bought from this seller last year and I was very very pleased. My son loves them. I bought 5 additional pairs. They are a bit expensive though but they are the only thermal I will invest in. My son will still be wearing the ones I got him last year even though they are a little short I may let him sleep in them. I will continue to support this seller and I was not paid for this review.

My son's clothes are almost all used. Very rarely do I have to buy him something as we are lucky that he has older cousins. However, I pulled out the long underwear set that he should have been able to wear, and it was scratchy and had shrunk terribly. So, I ordered these for him. I was happy to be able to find a brand made in the USA, and though it was a bit more than I would have liked to have spent on a single set of long underwear, I am glad I did. I am very pleased how soft they are. My son put them on and exclaimed that he was "comfy". I like that they are a 50/50 blend of cotton and polyester blend. They fit well even though I bought a size bigger to hopefully be used next year.

I bought these as a part of my son's Halloween costume for the color and the good price. I was very pleased to find that they are lightweight, well-made and SO SOFT. As soon as my son put them on he didn't want to wear anything else. He's worn them as pjs for several nights in a row. I've had to wash and hand them right back. I'm going to buy more in other colors for him to wear as pjs.

I bought a set of these for my 8 month old grandson because I wanted a "base layer" to go under his fleece sleeper when I pick him up in the morning. It's usually in the high 20's to mid 30's outside and this works great for our walk out to the cold car for the drive to and from his home. I wasn't sure how to keep him warm since the new guidelines are to not use heavy weight winter coats in infant car seats -- this plus a blanket seems to work great and he's very comfortable. I know it's working because before I bought this I would get him home and his skin would actually feel cold to the touch - now he's nice and warm (not hot and sweaty - just comfortable warm). I don't know if this will shrink or not because I line dry them.

Nos encantó que la tela es muy suavecita y las etiquetas se quitan fácil para que no le raspen al bebé. Es delgada pero cumple perfecto para mantenerlo calientito. Se la ponemos como una capa extra entre el body y la pijama en las noches y no ha pasado frío aun cuando se destapa de las cobijas.

No la he puesto a mi bebé, pero está muy bien la tela, me gustó mucho
