Copper Pearl Cooper Sleep Bag 0.5 TOG – Premium 3-Layer Knit Baby Sleep Sack

Cozy, breathable comfort you can feel

Introducing the Copper Pearl Cooper Sleep Bag, a thoughtfully designed three-layer knit that wraps baby in softness. The blend of premium polyester and rayon delivers a gentle stretch and breathable texture, helping the fabric move with tiny shifts while staying comfortable. This sleep sack offers a practical alternative to loose blankets, reducing the risk of fabric bunching and keeping a tidier nursery look.

The knit is described as buttery and soft to the touch, with a stable, even texture that provides a cozy, cushioned feel for your little one. You’ll notice the subtle weight and smooth surface, which many families appreciate during transitional seasons when a little extra warmth is welcome without overheating.

Designed for warmth and ease

The 0.5 TOG rating aligns with room temperatures around 74–78°F, making it a straightforward option for seasonal shifts or rooms with variable climates. The sleeveless cut supports comfortable movement and layering with other sleepwear as needed. Sized for newborns, the fit is crafted to stay comfortable without feeling too tight, while offering enough room for growth across the 0–6 month range.

Key functional touches include a comfy, tag-free neck and a top-to-bottom zipper for smooth on and off. These details are designed to streamline bedtime routines and mid-night changes without disturbing little sleepers more than necessary.

Fit, size, and style

This Sleep Bag is sized 0–6 months, with a length of about 28 inches, a chest width of 13 inches under the armpits, and a maximum width of 18 inches. The sleeveless silhouette keeps the layer light and easy to wear, while Copper Pearl’s prints bring a modern, nursery-friendly look that pairs well with other essentials.
