Woolino 4 Season Baby Sleep Bag with Feet Holes – Navy, Merino Wool & Organic Cotton

Premium fabrics for comfort from first nap to night-time sleep

The Woolino 4 Season Baby Sleep Bag with Feet Holes blends an Australian merino wool lining with a GOTS certified organic cotton outer. The lining is 100% natural, softly plush against delicate skin, while the outer layer offers gentle breathability. In a classic navy, this sleeping bag pairs well with your little one’s nightwear and nursery decor.

Year‑round comfort with temperature regulation

Merino wool is renowned for its temperature regulating properties, helping baby stay warm on cooler nights and breathable on warmer ones. This design supports a single sleep layer across all four seasons, reducing the need for extra blankets and bulky layering while encouraging restful sleep.

Designed for movement and easy changes

Foot openings provide mobility when your child is awake, while the generous cut allows feet to tuck in comfortably during sleep. A bottom zipper enables quick diaper changes, and the whole garment is machine-washable for busy households.

Sizes that grow with your child

Three practical sizes are offered: 6-18 months, 18-36 months, and 3-4T. This range accommodates a growing toddler and minimizes frequent wardrobe upgrades, helping you plan ahead for sleep-time needs.

Trusted quality and support

Since 2010, Woolino has been a leading name in baby sleep bags and is renowned as a top seller and reviewer favorite in the USA and Canada. The product includes a 6‑month warranty from a US company with US-based customer service for peace of mind.
