Woolino 4-Season Merino Wool Baby Sleeping Bag – Sage

Worried about which sleep bag to use for your baby? The Woolino Merino Wool and Organic Cotton Baby Sleeping Bag in Sage is designed for year‑round comfort, featuring natural temperature regulation and a grow-with-me fit. Available in three sizes (0-6, 6-18, 18-36 months), it eliminates the need for multiple sacks by adapting as your child grows.

Merino wool sits softly against delicate skin, breathing and regulating temperature to help baby feel warm when it’s cold and cooler when it’s warm. The outer shell uses organic cotton for a breathable, natural touch, creating a cozy, durable sleeping environment that respects sensitive skin and everyday wear. This combination is built for everyday use, easy care, and lasting softness.

Safety and quality are visible in every detail: the sack carries the OEKO-TEX STANDARD 100 label and Woolmark certification, reflecting rigorous testing and trusted textile standards. A classic no‑snap design with a two‑way zipper offers convenient dressing and diaper changes, while zipper guards protect tiny skin. When needed, the sleeping bag can open flat for quick access and easy layering adjustments.
