I bought my grobags from a website, can PM you the link if you wish. It has all the details on their in regards to the different togs. We live in one of the hottest places in Aust & because of this have the aircond on flat out 24/7, so Charlie is in a 1.0tog still with longsleeve suit underneath to keep his arms warm...no blankets needed & I love it. In winter I'll put him in long pj's, singlet & a 2.5 tog...that way I know he's toasty warm without the need of extra blankets (oh & a bar heater for the 3am chill).
