When the temperature drops, this is the one. Filled with 90% white duck down and rated extra thick, this one-piece snowsuit wraps your baby in serious warmth from head to toe — with a soft, non-scratchy shell that feels gentle against delicate skin.

One zipper. Full coverage. No gaps between jacket and pants. Perfect for stroller walks, outdoor outings, and everything in between.

✦ Down Fill Quality

Not all down is equal. Here's a quick guide to help you choose with confidence:

  • Goose down — the warmest and lightest, premium tier
  • White duck down 90% — high quality, excellent warmth-to-weight ratio, minimal odor ✔ This jacket
  • White duck down 85% / 80% — good warmth, more affordable
  • Grey duck down — similar warmth to white, slightly more odor-prone

90% white duck down sits at the top of the duck-down tier — a smart choice for babies who need reliable warmth without unnecessary weight.

✦ Shell Fabric

The outer shell is a triple-protection fabric: water-resistant, oil-resistant, and stain-resistant. Spills wipe off easily — no special care needed for everyday messes.

✦ How to Choose the Right Size

For down jackets, always size up rather than down. Here's how to think about it:

  • Babies grow fast — especially in the first two years. A size that fits perfectly in October may be too snug by January.
  • A winter coat is typically worn for one season only. Factor in how old your baby will be at the coldest point of the season, not just right now.
  • Sizing up also leaves room for a base layer or light sweater underneath, which is how down jackets are meant to be worn.
  • Example: If your baby is 8 months old now and winter runs through February, they'll be 10–11 months at peak cold — size 80 is the safer choice over size 73.

✦ Materials

  • Shell: 100% Polyester (triple-protection finish)
  • Fill: 90% White Duck Down, 10% Feather

✦ Care Instructions

Hand wash or gentle machine wash cold. Tumble dry low with dryer balls to restore loft. Do not bleach or iron.
