This warm 3.5 tog weight bag is perfect to keep your little ones snuggly warm in the cooler Winter months while still having them safe in a beautiful quality sleeping bag for your peace of mind.

These are warm and cosy bags, suitable for bedrooms approx 14 to 20 degrees. 

These beautiful and super soft bags are carefully made to our standards and specification, from organic cotton blended with elastane for durability and comfort with easy care, quick dry polyester filling. The bags are a generous size and have under-arm domes meaning a safe and comfortable fit for when your child is in a new size for the first few months. The high quality open end YKK zip be unzipped from the bottom and opened upwards for easy nappy changes. It also has a zip guard to avoid any 'zipping' accidents.

The beautiful prints you see are hand created in our Auckland office! They come packaged in an awesome compostable bag. Designed to be reused before popped into the compost. They have a zip lock feature allowing them to be used until they get tired and ready for your home compost system!

Tips on how to measure your child
Height/Length - Our height measurement doesn't include a child's head and neck length. Standing straight with a flat foot measure from the base of the heel up to either the top of the shoulder. You may find it easiest for younger children to stand with their back to a wall to do this. Make a small pencil mark on the wall at either the top of the shoulder or head and ask the child to step away before measuring from the floor up to the pencil mark.
Chest - Place tape measure under the arms and measure around the chest at the fullest part until your fingers meet.

Please note - Measurements are taken when garments are laid flat. Areas such as chest and armhole are calculated at twice the width to get the full measurement.

Materials & Care

Shrinkage can occur if the water is too warm or drying temperature is too high
Line dry is preferred - use a low setting if tumble drying
