SwaddleDesigns Organic Transitional Swaddle Sack — Arms Up Sleeves, Half-Length, Small (0-3M), Jadeite

Soft, Safe, and Flexible Sleep Solution

The Organic Transitional Swaddle Sack helps families ease baby from a traditional full-swaddle state while supporting a familiar arms-up comfort. The sleeves are designed as 1/2-length with foldover mitten cuffs that can be opened or closed, enabling self-soothing with hands when desired, or extra protection from facial scratches. The fabric is 100% organic cotton and GOTS certified, delivering a soft, breathable feel that stays gentle against delicate skin night after night. With a 0.5 tog rating, it offers balanced warmth for moderate room temperatures, and layering under a bodysuit or another wearable blanket is a practical option when nights turn cooler.

SwaddleDesigns draws on nursing experience to shape a product that emphasizes baby comfort and caregiver ease. The two-way zipper with a protective guard allows smooth entry and simple diaper changes from top to bottom, keeping routines calm for both baby and parent. The sack’s unique design supports a flexed, natural arm position while still permitting mobility if your baby begins to roll, a feature that many families find reassuring during the transition away from a fully restricted swaddle.
