The fabric feel

Our signature bamboo viscose is milled to be twice as soft as cotton. It has a silk-like drape and a cooling touch that calms fussy babies instantly.

Fit & sizing

Designed with a grow-with-them fit for sizes 3M-24M.

Washing instructions

Wash cold and tumble dry low to keep the bamboo soft and smooth.

Just put the T-shirt on our 3 month old. It’s AMAZING! His tummy doesn’t show the fabric is so soft and the fit is true to size. Love the product will definitely be getting more.

Finally, a shirt that stays put.

The Tee that works like a onesie.

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.

Bamboo so soft moms keep checking the label to make sure it is clean.

Sized 3M-24M so you are not re-buying every six weeks.

The Science Behind the “Onesie Tee”

  1. 1

    Snap-Tucked™ bottom

    A soft underlayer that snaps clean below the diaper, so the tee can’t ride up.

  2. 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. 3

    Grow-with-Them Fit

    Bamboo fabric’s stretch and recovery means each size lasts longer than a typical cotton tee.

  4. 4

    Gentle on Skin

    Naturally smooth and hypoallergenic, ideal for sensitive baby skin.

Customer photo review of Staple Onesie Tee

These shirts are perfect! The quality is impeccable, to the point where I don’t want the boys the ruin them!! They are so soft, nicely made, and clean up very well. Thank you for distributing a quality product! Also, they have room to grow into them which makes me happy as they will be able to wear them for longer! The twins approve!

Customer photo review of Sweatshirt Onesie + Sweatpant Set

We love this set! The material is thick but soft and stretchy. My son is big for his age, at 14mo he's 33in and almost 30lb. The 18-24m set just fits. I wish I would've found these clothes when he was younger!
