We recommend sleepwear made of natural and breathable fabrics like cotton or merino wool.
Please refer to the dressing guide we provide (shown below, and also on back of your Woolino room thermometer) for general recommendations on how to dress your baby depending on the room temperature. The temperature in most rooms will rise and fall throughout the night, and the merino fiber has the remarkable ability to regulate your baby&apos;s body temperature.

We consider short sleeve sleepwear to be items like tops, bodysuits, and onesies. These &quot;sleepwear&quot; items don&apos;t have legs and are generally more lightweight for use in warmer temperatures.
Pajamas are one and two-piece sets (tops and bottoms) that are generally warmer and thicker than most sleepwear items. Our dressing guidelines are provided as general recommendations only as every child is different. We strongly recommend touching your child at the back of their neck or their stomach while sleeping to gauge their temperature and level of comfort.

What to wear when sleeping in a Woolino 4 Season Sleep Bag?

Woolino 4 Season Baby Sleep Bags are designed as wearable blankets to be worn over sleepwear. They are suitable for room temperatures of 63-75&#xB0;F (17-24&#xB0;C) with our suggested dressing guidelines. These guidelines are general since all children are different, and their tolerance to temperature may vary.
Merino wool, used in these sleep bags, is excellent at regulating temperature. It is important to ensure that your child wears clothing appropriate for the nursery temperature underneath the sleep bag. Each 4-season sleep bag includes a nursery thermometer and dressing guide to help parents choose the right layers of clothing to keep their child comfortable throughout the night. These are only recommendations as each child is unique, and the layers required for a comfortable night&apos;s sleep will vary from baby to baby. Natural, breathable fabrics like organic cotton, linen, bamboo, or merino wool are recommended. Polyester or micro-fleece sleepwear is not recommended as they are poorly breathable, may cause overheating, and block the merino wool liner&#x2019;s ability to create a comfortable micro-climate around your child.
To gauge your child&apos;s temperature and comfort while sleeping, touch the back of their neck or their stomach. Hands and feet are not strong indicators of core body temperature. Monitor their sleep with the sleep bag at nap time. Check for signs of overheating such as sweating, a warm tummy, or flushed cheeks. If your child seems too warm, adjust their undergarments accordingly.
For warmer climates or nights, Woolino also offers Organic Cotton Sleep Bags. These options include:
<ul>
<li>Ecolino Adjustable Sleep Bag: Made with two layers of organic cotton, ideal for nurseries with room temperatures of 69-76&#xB0;F (20-24&#xB0;C).</li>
<li>Ecolino Basic Sleep Bag: Made with one layer of organic cotton, recommended for room temperatures of 72-77&#xB0;F (22-25&#xB0;C).</li>
</ul>

Our 4 Season baby sleeping bags are designed to be worn year round. They are made from 100% natural breathable fibers and contain NO synthetic filling. Therefore, they do not have a fixed TOG. The fine merino wool lining helps naturally in regulating baby&#x2019;s body temperature, keeping baby warm in winter and cool in summer.
Woolino sleep bags are recommended to be used in room temperatures&#xA0;63-77F (17-25C). Simply adjust the layers of sleepwear worn under the sleeping bag to suit the nursery temperature. You can find our suggested dressing guidelines on the back of the room thermometer that comes with every baby sleep bag.
