Inspired by Roberta Bondar

Roberta Bondar became the first Canadian woman in space in 1992, conducting experiments aboard the Space Shuttle Discovery. A neurologist, photographer, and explorer, she proved that the sky is never the limit. This onesie celebrates her journey from small-town Ontario to the stars.

Designed for Comfort

Our space-themed baby onesie features a dreamy print of planets, rockets, and constellations that will fuel your little one's imagination. Made from 100% organic bamboo cotton, the fabric is whisper-soft and gentle on sensitive newborn skin.

Thoughtful Details

Every Bondar onesie includes a two-way zipper for easy diaper changes, plus foldover feet for warmth. The snug-fit design is built for safe, comfortable sleep without flame retardants — just pure, natural cotton next to your baby's skin.

Ethically Made

Stemmewear is proudly woman-owned and Canadian. Our products are ethically manufactured with fair labor practices. A portion of every purchase supports girls in STEM education through our charity partners, including Plan International and Girls Who Code.

Sizing

Available in Newborn, 0-3 months, 3-6 months, and 6-12 months. Please ensure a snug fit as flame retardants are not used in production.

    I bought this for my friend's 2.5 year old daughter and she absolutely LOVES it! My friend told me it's the first pair of pyjamas her daughter will always pick out of her closet to wear because it's SO soft! Thank you Stemmewear for creating a product that's so comfy and promotes education. Amazing company — I will definitely buy more!
