Sleeveless Muslin Sleep Sack for Baby, Bamboo-Cotton Blend for Warm Nights
Details
Warm nights sleep so much better when your baby's skin can actually breathe. This sleeveless sleep sack is woven from a soft, airy muslin blend, made to replace loose blankets with a snug, safe cocoon that keeps your baby comfortable right through the night instead of overheating halfway through it.
Features
- Bamboo-cotton muslin blend — 70% natural bamboo fiber and 30% cotton for a silky-soft feel and genuinely breathable warm-weather comfort.
- Bottom-up two-way zipper — makes nighttime diaper changes quick and discreet without exposing your baby's chest to cool air or waking them fully.
- Roomy, sleeveless cut — leaves plenty of space for arms, hips, and legs to move and kick freely as your baby grows.
Built to grow with your baby
At 29.5" (75 cm) long, this sleep sack is sized to comfortably fit babies from 0 up to 24 months, so it earns its keep well beyond the newborn stage. A soft protective flap sits over the top of the zipper, keeping the zip pull away from your baby's chin and neck at all times.

Easy to keep clean
Busy nights call for simple care, so the whole sleep sack is fully machine washable and holds onto its softness and shape wash after wash — no special handling routine required.
