Maccie Winter Sleep Sack

The Maccie Winter Sleep Sack is a wearable blanket made from soft bamboo, designed to keep babies and toddlers cosy on cooler nights without the need for loose blankets in the cot. Rated at 2.0 TOG, it suits cool nurseries between 16°C and 20°C, giving you a warmer sleep sack for winter and cooler climates while your little one stays safely enclosed.

Bamboo is the reason this sleeping bag feels the way it does: naturally breathable and cloud-soft, it helps wick moisture and can help reduce the sweating and irritation that sometimes disturb sleep. That makes it a gentle option next to delicate skin, and one that many parents reach for when a baby has sensitive or eczema-prone skin.

Bamboo fabric that breathes

Made from 97% bamboo viscose blended with 3% spandex, the fabric is soft to the touch and naturally breathable, offering a natural-fibre alternative to stiffer cotton or synthetic polyester fleece pouches. The bamboo helps wick moisture away rather than trapping heat and dampness against the skin, so your baby can stay comfortable through the night.

A roomy, hip-healthy cut

Instead of the narrow, restrictive feel of some infant sleep suits, the Maccie sleep sack has an extra-wide bell bottom that gives active sleepers full freedom of movement. The small amount of spandex adds a generous, hip-healthy stretch that encourages natural sleep positions, so there's plenty of room for wriggling while your little one stays snugly covered.

A secure, considered fit

The chest is snug and fitted, with precise neck and arm openings that are designed to keep the fabric from shifting or slipping up over your baby's face. It's a thoughtful detail that keeps the sleep sack sitting where it should throughout the night.

Easy night-time changes

A two-way zipper lets you open the sleep sack from the bottom for quick nappy changes, so you don't have to fully undress your baby during chilly nights. Zipping up completely also protects the inner quilting and helps the sleep sack hold its shape wash after wash.

Layering underneath

How you dress your baby underneath makes all the difference to getting the warmth right. As a general guide:

• For 18°C–20°C: a standard long-sleeve bodysuit.
• For 16°C–17°C: a long-sleeve onesie plus a vest or short sleeve.

It's available in three sizes to grow with your child: 0–6 months (65 cm), 6–18 months (90 cm), and 18–36 months (100 cm). It's machine washable on a cold, gentle cycle, and best hung or laid flat to dry rather than tumble dried.

Pandylane Pro Tip: To check whether your baby is dressed right, feel the back of their neck — if it's warm and dry, the layers are working well.

A note on safe sleep

A sleep sack is designed to replace loose blankets in the cot. Follow safe-sleep guidance by placing your baby on their back on a firm, flat, level surface in a clear sleep space, and choose the size that fits correctly at the neck and arm openings. Check the fit regularly as your child grows.
