The Baby Retro-X Vest is windproof, warm and crafted of soft 1/2-pile fleece. Think of it as a fleece furnace for smaller torsos. We've cleaned up this heritage style, for both adults and kids, by using 100% Repreve recycled polyester certified by OceanCycle and sourced from coastal communities at risk of plastic pollution. The stand-up collar is lined with fleece for tactile next-to-skin warmth and trimmed with recycled nylon fabric for classic Retro-X style. Since these styles tend to become favorites, we've included a hand-it-along ID label for generations of stories and wear. Made in a Fair Trade Certified factory. | Patagonia Baby Retro-X Fleece Vest in Dark Natural, 4T - Recycled Nylon/Recycled Polyester
