Frequently Asked Questions
Does bamboo really help with eczema?
Yes. Bamboo fibers are incredibly smooth and round, which means they do not have the microscopic hooks that cotton or wool have. This reduces friction against the skin, helping to calm flare-ups.
Are the snaps nickel-free?
Absolutely. All our hardware is nickel-free and lead-free to help avoid skin irritation.
Will it shrink in the wash?
Our bamboo fabric is pre-washed to minimize shrinkage. Wash cold and tumble dry low to keep the tee soft and smooth.

The Science Behind the “Onesie Tee”
-
1
Snap-Tucked™ bottom
A soft underlayer that snaps clean below the diaper, so the tee can’t ride up.
-
2
Bamboo Fabric
Ultra-soft, breathable fabric that naturally regulates temperature and stretches with baby’s belly, hips, and rolls instead of fighting them.
-
3
Grow-with-Them Fit
Bamboo fabric’s stretch and recovery means each size lasts longer than a typical cotton tee.
-
4
Gentle on Skin
Naturally smooth and hypoallergenic, ideal for sensitive baby skin.

So cute, soft, and easy to put on him! Immediately went back to buy long sleeve versions.
These shirts are a game changer for wiggly little ones!
I love sweat suit outfits! I hope it lasts him a while he is 8 months
Ultimate comfort. Such a cute set that got so many compliments! I love the built in onesie so the sweatshirt doesn’t ride up
Cannot rave about these enough! We want every single shirt offered. We live in these, and now I don’t want to put anything else on my little one. It’s so soft and stretchy. True to size and stays down. Love love love!
They are soooo amazing !!!
We love this set!! I’ve always hated the look of just a onesie with pants but this is perfect combo, and easy to get on! Also so soft!
Onesie Sweatshirt Top & Bottom Set
Store owner replied: Yay! We’re so happy you love it! We totally get it—onesies and pants don’t always work well together, which is exactly why we created this set. So glad you’re loving the softness and ease too! Thank you for your support!
The absolute softest clothing- great fit. My kid loves wearing this set. He always gets a lot of compliments when he’s in it. Don’t hesitate to buy this- you’ll find yourself reaching for it constantly.

Good quality. Runs a bit smaller than some brands. You may want to consider sizing up.
First time ordering and I was very impressed with my purchase
Loved the shirts. Great quality.
This is the softest material, best customer service experience I ever had. My package was lost and they replaced it right away. It was so speedy and the short we purchased was great quality and our baby is so cute!
I love this sweat outfit but it seems to be a little smaller compared to the other items I purchased at 6-9months. But otherwise I love it !
Absolutely love this sweatsuit! So soft and comfy! We had it in a smaller size and just bought a bigger size for my son as it was one of our favorites! Highly recommend.
