PREMIUM FABRICS FOR NATURAL COMFORT – Meet the Woolino 4 Season® Ultimate Baby Sleep Sack, made with a 100% superfine Australian merino wool lining and a 100% GOTS organic cotton outer layer.

Naturally breathable and moisture-wicking, merino wool helps regulate your baby's body temperature, helping keep them comfortable through the night. Designed for year-round use, this all-season baby sleeping bag takes the guesswork out of choosing between different TOG ratings and helps ease your worries about your baby getting too hot or cold as nursery temperatures change. SAFER SLEEP, MORE PEACE OF MIND – Soft and gentle on delicate skin, Woolino's merino wool sleep sack does more than replace loose blankets in the crib. Its uniquely breathable merino wool helps keep your baby warm when it’s cold and comfortable when it’s warm.

That natural temperature regulation means more comfortable sleep for your little one and one less thing for you to worry about at night. ONE SLEEP SACK. TWO YEARS. FOUR SEASONS. – Why keep buying different sizes and weights? Woolino's Ultimate Baby Sleep Sack features a universal size that fits babies from 2 to 24 months, growing with your little one through every season.

Durable, machine-washable, and designed for everyday comfort, it's a smarter alternative to buying multiple sleep sacks. For older toddlers, the Ultimate Sleep Bag is also available in a 2-4 year size.
