Does this now mean my 2.5 Tog isn’t thick enough for winter?

The 2.5 Tog which we describe as an All Year Round product is suitable for most room temperatures in the UK (16-20 degrees). However over the past couple of years our customers have been asking us for something thicker for winter when they have noticed really cold temperatures. Hence, we have created the 3.5 Tog. If you only have a 2.5 Tog, we recommend trying to keep the room temperature your baby is sleeping in within the 16-20 degree range, and layering the clothing under their Grobag accordingly.
