    • Cozy and weirdly sized
Color: Red Size: Small
I'm so on the fence about how to rate this! - My son absolutely loves these. I might buy another pair he loves them so much, BUT . . . - My MIL had to take the waist in by INCHES. He's 5 years old, about 42lbs and 44 inches tall (A lean little boy, I know). We got him the small and they fit like jammies. If I do get another pair it will be the XS so they fit better under his clothes. The waist was seriously ridiculous and there won't be a time when it won't be. If he's tall enough for the waist, the pants would be capris. Comfort is absolutely 5 stars, though. The fleece lining is cozy. Because my son's so lean he gets cold easily during our winters, and he stays toasty warm with these on. So, they do their job very well. tl;dr? I love these IF you have someone handy with a needle. ... show more

    • Best Thermals Ever
Color: Blue Size: X-Small
When folx say their kids love these thermals they aren't making it up. I bought one pair for my 5 year old (who has sensory sensitivities) to try, and now he basically lives in them. Softy and cozy; definitely warm. I ended up needing to order two more pairs so I could actually WASH them between uses. He thinks he has gotten away with something amazing when he can leave the house still wearing the thermal top (still gotta wear some regular pants my love...). My only request -- please make these in pink next, please! Highly, highly recommend. ... show more

    • 6 yr old loves how cozy and soft they are.
Color: Jade Size: Small
As soon as we tried them on my son kept saying how soft and cozy this set was. They are pretty stretchy and lightly lined with fleece on the inside. The color of the green was a little more teal than the picture showed, but we are ok with that. The waist is larger for the size, but somehow stays on my thin 6yr old when wearing the shirt with it. My son wears true to size (6) and we ordered a Small. It fits well enough but there’s plenty of room to grow. ... show more

    • Poor stitching
Color: Black Size: X-Small
These arrived on time and fit as expected. The only thing I have an issue with is the fact that the stitching was poor. The crotch wasn’t sewn at the inseam and there was material pulling out at the waistband where a stitch was missed. My kid likes them so that’s all that matters but attention to detail would have been appreciated ... show more

    • Warm, but ran big
Color: White Size: Small
My small 6 yo is 43" and 39#. The size small top fit fine, but the bottoms were really big. He ended up only using the top. Material and quality was good, just too large to wear.
