HOT ! All Season Wool Sleep Sack

Your baby\'s temperature changes throughout the night. Most sleep sacks can\'t keep up — they hold a fixed amount of heat and leave you guessing. This one doesn\'t.

The Goldie Kids All-Season Wool Sleep Sack is made from Canadian wool — a naturally thermoregulating fibre that releases heat when your baby warms up and retains warmth when temperatures drop. One sleep sack, all four seasons, no swapping.

The exterior is a premium Tencel blend jersey — exceptionally soft against skin, breathable, and gentle enough for sensitive babies. The interior wool layer does the temperature work. Together they create a sleep environment your baby can stay comfortable in all night, regardless of what the room does.

Designed to grow with your child from 2 to 24 months through adjustable snaps. Works in strollers. Made in Canada.
