Supima® cotton is the finest cotton in the world — grown exclusively in the USA and representing just the top 1% of all cotton produced globally. Its extra-long fibers make it up to 35% softer and 45% stronger than regular cotton. For babies, whose skin is thinner and more absorbent than adult skin, this difference is significant. Supima® cotton is naturally smooth, breathable, and free from synthetic blends — making it the gentlest choice for everyday wear.

Yes. KottonSpa™ products are trusted by NICU moms for their exceptional gentleness. Our skin-first design means pure Supima® cotton is the only thing that ever touches your baby's skin — no synthetic linings, no rough embroidery threads, no irritating seams on the inside. Every decorative detail is placed on an outer layer only, so comfort is never compromised.

Most baby clothing brands use standard cotton, bamboo blends, or synthetic fabrics. KottonSpa™ uses only 100% US-grown Supima® cotton — across every product, every collection, without exception. We don't blend, we don't cut corners, and we don't use chemical coatings or treatments. Every design decision starts with one question: is this good for baby's skin? That commitment is what sets us apart.

Yes. Sustainability is woven into everything we do. Our Supima® cotton is grown in the USA under strict environmental and ethical standards. We are proud partners of Tree-Nation, actively contributing to global reforestation with every order. Our supply chain is SEDEX-audited for ethical sourcing, and we continuously work to reduce our environmental footprint — because the world your baby grows up in matters just as much as the clothes they wear today.

KottonSpa™ offers two signature fabric collections — Supima Stretch Knit and Supima Muslin — each available across a range of styles including bodysuits, onesies, rompers, jumpsuits, swaddles, hooded towels, and accessories. Every piece is crafted from 100% US-grown Supima® cotton and designed for your baby's everyday comfort, from the first days home to every milestone that follows.

Machine wash cold on a gentle cycle and tumble dry low. Do not bleach. No fabric softener needed — Supima® cotton softens naturally with every wash, so your baby's clothes get better the more you use them.
