Great
Just what I was looking for for my son’s school. This two-piece sweatsuit set (sweater and pants) is very comfortable, keeps him warm, and looks great quality.

Just right for Fall Baseball, layering
It was comfortable, warm and enough movement for baseball in the fall. Good quality. Ideal for layering.

Very comfortable & thoughtfully designed!
So soft and warm!This set has the perfect amount of thickness—not thin and cheap, and not so thick that you’ll feel uncomfortable.. just thick enough to feel warm, soft, and really cozy. I was very pleasantly surprised by the feel of both the top and bottom.The quality seems to be great! I imagine they’ll hold up just fine with regular wash and wear.The blue color is just as bright and vibrant as it looks in the product photos and the coloring is consistent throughout.These have the perfect amount of stretch— easy to function in no matter what you’re doing, while still keeping you warm. The inside is very soft, has a bit of a fuzzy feel to it (see pic #5 & #6; I tried to get an angle that shows the softness of it) so it doesn’t make me sweat like the ones where the outer material is the same as the inner.The thumb holes are a nice addition; I’m a sucker for those, and they are lined up in a comfortable spot—doesn’t over-twist the sleeve when using the thumb holes, which I appreciate. And if a male is wearing them, the opening there is fully functional as well which makes bathroom visits quicker and easier.. and warmer, I’d imagine lolI would definitely recommend to anyone that needs added warmth that still allows you to move around like you normally would. The sizing seems right to me so I would order your normal size or a size up (i think the stretch would allow it to still fit close to ya, but with a bit of growing room). I would say the XL here could double as an adult small, but of course that depends on your particular build. I’m usually an adult medium in clothing that isn’t meant to fit real close, and the XL in these fit just right.Definitely worth the price (imo), as similar sets can go for almost double.. which is nuts. This price seems fair and the quality seems great. I’m of the mind that you shouldn’t have to break the bank to get decent quality clothes, so this is just right for me and my wallet lol This is the kind of thing I would stock-up on, and it would also make a great gift. There’s only the blue color currently, but if they had other colors I’d probably get one of each— but I’m not above just stocking-up on a couple blue sets lol

Soft and stretchy
These are a polyester and spandex base layer top and bottom set. Polyester won’t keep you as warm as natural fabrics, but layered with other items it does a good job trapping in the heat and wicking away moisture. The added spandex helps with putting on and removing.I ordered size XL, which is typically a bit large for my son. At the time I ordered there was no size chart on the listing (there is now). The top fits great, a typical boys XL bar layer size. The pants are SMALL. when compared with his joggers, these are a full 3 inches shorter. I know since they’re a base layer they won’t be as long, but these won’t even come to his ankles.I do like the wide waist band and open fly the pants have. These are details some of his other sets don’t have. The fabric of this is also a bit thicker And softer than others.I’m not sure how to remedy the short pants issue for those who are ordering this in the future, as it’s really a choice between short pants or an oversized top.

Very good quality and great seller attention
Had to send the first pair back as I ordered the wrong size. Return was amazingly simple! Requested one and immediately got confirmation and qr code to show at UPS. Dropped off in the original package and received approval for refund within a couple of hours. Ordered another pair ( different size) and will get delivery within days.Thermals are the perfect bright red and well made with flat seams and well situated thumb holes. Very smooth exterior and soft warm feeling interior. The functional fly is great too. Got this on sale and worth it even at full price (but who doesn’t love a sale?)Can’t wait till he opens them. No more too cold camp outs

Very warm, double layered, thumb holes, little compression; maybe size up 1x
the outside is a nice, sleek look. they have a great, deep, dark blue color, thumb holes, to help keep the hands a little warmer, too. There is an inside layer of fleece, maybe, or a flannel? not sure, but it helps keep your l/o much warmer than some thin, single layered set. This one is quality. I rather like it. It does seem to be a compression version though. I would size up if you want it to be loose fitting and not constricting. Just be mindful of the longer sleeves and pant legs a bigger size will bring.

Soft and easy to layer
This Poekuao Boys Thermal Underwear is a soft, good quality garment. The waistband, neckline, seams, and thumb cuffs are all good. Fabric is soft with smooth outer surface and a micro fleece-like inside surface which will add on a layer of warmth. It is a good slim fit.
