Sleep Sacks

Is your little one waking up cold in the middle of the night because they’ve kicked off their blankets? You are not alone. Transitioning from a snug swaddle to independent sleeping is a huge milestone, but it often brings the worry of loose bedding. At SwaddleAn, we believe safer sleep leads to sweeter dreams. As part of our complete Baby Sleepwear collection, our Sleep Sacks (also known as wearable blankets) are designed to replace loose blankets in the crib, providing the cozy security your baby needs without the safety risks.

Why Switch to a Sleep Sack?

The American Academy of Pediatrics (AAP) recommends keeping soft bedding, including traditional blankets, out of the crib for at least the first 12 months to reduce the risk of SIDS. A sleep sack is the perfect solution. It acts as a safe, wearable blanket that can’t be kicked off or pulled over your baby’s face. Whether you have a wiggle worm who explores every corner of the crib or a peaceful sleeper, our sacks ensure they stay covered and at a comfortable temperature all night long.

If your baby is still a newborn and hasn't started rolling over yet, you might want to explore our Swaddles collection first for that womb-like containment.

The "Viscose from Bamboo" Difference

Overheating is a known risk factor for babies. That’s why we craft our sleep sacks from premium Viscose from Bamboo. This fabric is a game-changer for infant sleep:

• Temperature Regulating: It naturally adjusts to your baby's body heat, keeping them cool in summer and warm in winter.

• Hypoallergenic: Gentle on eczema-prone and sensitive skin.

• Butter-Soft Feel: Softer than organic cotton, providing a cloud-like touch that calms fussy babies.

Pro Tip: Wondering what to wear underneath? Pair our sleep sacks with our breathable Baby Pajamas for the ultimate sleep system.

Choosing the Right TOG for Every Season

"TOG" stands for Thermal Overall Grade, which indicates how warm the sleep sack is. We offer specific weights to match your nursery's temperature, so you never have to guess.

Designed for Parents, Approved by Babies

We know that a diaper change at 2 AM needs to be fast and silent. That’s why every SwaddleAn sleep sack features a 2-way J-shaped zipper. You can unzip from the bottom for a quick diaper change without exposing your baby’s chest to the cold air or fully undressing them. Plus, our generous bell-shaped bottom design is recognized as "Hip-Healthy," allowing plenty of room for your baby to kick and fold their legs naturally.
