I use the snugtime (i think thats the name) available from myer - mum bought me a new one last week for winter it cost $35 and Alyssa is nice and warm in it (has long sleeves) it also has the seatbelt hole.

Just saw a bunch on ebay - all kinds of brands - just search baby sleeping bags
I think you are talking about the "snugtime" grobags.. I have them for my kidlets up to size 5 they loves them and they are snug and warm.
I have just ordered mine for Ethan so they should be here soon
I just bought what you are asking about yesterday from Sids and Kids and am looking forward to it's arrival! <span class="emoticon smile">smile</span>
Here it is here with a better description at this site compared to the Sids and Kids one for those interested in it! Bubbles Travel grobag
I hope that this is what you were asking about.
All the best with it! xox
