Sizing and Fit
Sizing and Fit
Our products intentionally run larger, so that your little one can wear them for longer. We recommend purchasing items more “true to age.” Our 12-18 month size is comparable to an 18-month Carters product.
Materials
Materials
50% cotton, 40% poly, 10% PurThread.
Purthread safely embeds ionized silver into filament yarn to help fight the bacteria that cause odor, mildew, and more. This keeps clothes smelling fresher and lasting longer, even after hundreds of washes.

Care Instructions
Care Instructions
Wash however you wash. You already have a lot on your plate :)
For optimal results, we recommend machine washing in cold water and drying on low.










Pack lighter and breath easy
Our quick-drying performance fabrics are designed to stay fresh through dribbles, spills, and sweat. That means fewer changes and fewer washes; a win for your family and the environment.
Avec ses manches longues et son tissu léger, ce chandail aide à protéger du soleil. C’est un gros coup de cœur! Je viens d’ailleurs d’en commander de nouveau en vue de l’été.
La taille du vêtement correspond bien à l’âge de chacun de mes enfants.
I wasn’t sure if we would love this shirt. It felt almost too soft. Like it would rip very easily. But it is very tough and durable. The thumb holes are fun and make it easy for layering. And the snaps keep it from getting stretched out at the neck. The color is a little pale for my preference, but that does make it easy to match with lots of pants and jackets. It is easy to get out food stains and gets dry quickly. We will definitely get this again in a darker color.
