SwaddleDesigns 6-Way Omni Swaddle Sack – Arms Up Newborn Sleep Sack (0-3m, 12-18 lbs)

Calm, comfortable, and flexible: the Omni Swaddle Sack

The SwaddleDesigns 6-Way Omni Swaddle Sack is a nurse-designed sleep solution crafted from soft 100% cotton knit. It offers growth-ready tailoring that supports natural arm positions and breathable comfort. From a snug arms-down wrap to arms-up configurations for self-soothing, this sack adapts as baby grows, helping newborns feel secure while remaining comfortable enough for healthy movement.

Versatile swaddle options for growing babies

The Omni Swaddle Sack provides multiple ways to swaddle beyond a traditional wrap. You can choose from (1) arms on the chest under the wrap for a classic snug hold, (2) one or both hands up for soothing proximity, or (3) both arms up and outside the wrap for a self-soothing path as baby learns to calm themselves. The half-length sleeves with mitten cuffs can be opened or closed for warmth, facial protection, or easier access to hands for soothing.

• Arms-on-chest swaddle preserves the classic snug feel, helping newborns settle quickly.
• Arms-up configurations support self-soothing opportunities when baby is ready.
• Foldover mitten cuffs provide adjustable warmth and scratch protection.
• Hip-friendly wrap design allows natural leg movement during sleep and diaper changes.

Smart design features that make night-time care easier

Key design elements include a two-way zipper that unzips from foot to diaper area and from the top for fast, calm diaper checks without fully unwrapping. The wrap is narrow and avoids restricting hips or legs, while soft hook-and-loop fasteners secure the wrap without excessive fiddling. Baby can be placed in the sack with a simple unzip-and-slide, and parents can monitor diapering without waking sleepy little ones.

• 2-way zipper reduces disruption when checking diapers or changing outfits.
• Adjustable wrap keeps baby comfortable without squeezing hips.
• Mitten cuffs provide warmth and scratching protection as needed.
• Soft, breathable 100% cotton knit keeps baby cool and cozy.

Care, safety, and everyday practicality

Designed by a nurse and celebrated for its safe-sleep orientation, this sleep sack has earned attention from hospitals for promoting careful sleep practices. The Omni design is recognized with patents and international protections (US Patents 11,659,870 and D924,539; EU, UK, Canada, and others). The fabric is machine washable and durable, with a 1.0 TOG suitable for moderate warmth when paired with a bodysuit or lightweight pajamas. It’s available in two sizes: Small (6-14 lbs) and 3m (12-18 lbs), letting you grow with your baby without switching to a completely different style too early.

• 100% cotton, breathable and soft against delicate skin
• Machine wash and tumble dry for convenient care
• Two sizes help you plan growth without rushing transitions

Practical notes for parents

As babies begin to show signs of rolling, the AAP recommends stopping restraint with a swaddle or wrap. When you’re ready, you can transition to a different SwaddleDesigns product for continued comfort as your baby explores new sleep steps.
