Copper Pearl Sleep Bag

The safer, cozier alternative to loose blankets. Copper Pearl sleep bags wrap baby in three layers of buttery-soft knit fabric with just the right amount of stretch — warm enough for year-round use, breathable enough for a full night’s sleep. Because well-rested babies (and parents) deserve the best.

3-Layer Polyester/Rayon Knit Blend | 1.25 TOG Rating | Sleeveless Design | Tag-Free Neck | Top-to-Bottom Zipper | Available in 0–6 Months & 6–12 Months

The 1.25 TOG rating is ideal for room temperatures between 65–75°F, making this a true year-round sleep essential. The sleeveless design allows arms to move freely while keeping the body warm. A tag-free neckline means nothing scratching against baby’s skin, and the full-length zipper makes middle-of-the-night changes quick and painless.

Styling Suggestions

• Layer over a long-sleeve onesie on cooler nights for added warmth without overheating
• Pair with a matching Copper Pearl swaddle blanket for a coordinated nursery look
• Gift alongside a Copper Pearl bandana bib set for a complete, print-matched newborn bundle
• Use as a standalone sleep layer on warmer nights — the breathable knit keeps baby comfortable without overheating
• Style with a coordinating Copper Pearl print for a nursery aesthetic that carries through every sleep routine

Fit & Sizing Notes

True to size for the age range listed. The generous cut allows room to grow without being so roomy that it poses a safety concern. Made from the same ultra-soft knit as Copper Pearl swaddle blankets — gets softer with every wash.
