When to use a Gro-suit

Gro-suits are intended for use in cold wather in room temperatures of 18°C (65°F) or under, and are most suited for use with a 2.5 tog or 3.5 tog Grobag.

This information is for guidance only

Nursery Temperature3.5 tog Grobag2.5 tog Grobag
Under 18°C (74°F)   Gro Suit
Under 16°C (61°F) Gro Suit Gro-suit and sleeveless bodysuit or short-sleeved bodysuit
Under 14°C (57°F) Gro-suit and sleeveless bodysuit or short-sleeved bodysuit  

Why don't Grobags have sleeves?

The British Safety Standard dictates that a baby sleep bag shouldn’t have sleeves to allow ventilation around the chest area and to prevent children from overheating. All Grobags meet the British Safety Standard, so you won’t find a Grobag with arms!

Choosing a size

How to wash

All Gro-suits can be machine washed at 40°C. They can be hung out to dry or tumble dried on a low setting. As with all cotton goods, we have designed our Gro-suits to allow for up to 5% shrinkage. If your child has any allergies and you wish to wash your Gro-suit at 60°C, you should allow for a little more shrinkage. When washing, it is best to keep the zip closed. You can iron your Gro-suit on a low heat if desired, always keeping the iron away from the zip or covering the zip with a cloth. We recommend that you wash dark colours separately for the first few washes. We also recommend that you wash your Gro-suit with a detergent that is free from bleaching agents in order to retain the original colours.
