After looking at alternatives (here in Sweden) we found this bag to be the best at a reasonable price. And the price got even more reasonable by ordering from happybags.

Great quality product for mums and dads to use. Well worth £45.

The main reason for buying this bag was the room for "your stuff" as I did not want to carry a change bag and a handbag. Although it does have pockets for this reason they are quite small, it does have individual spaces for credit cards, pens etc but not adequate space to keep a wallet or purse. Also the hold on the strap is also small and does not hold my keys (they are quite bulky) or iPhone - it would hold a phone such as a Razor. It is however a fantastic bag for holding the baby's things - it has plenty of pockets for holding everything you need, the separate department for dirty nappies is a great idea. The change mat is probably my favourite feature - it attaches to the front of the bag in it's own pocket to keep it separate from from the rest of the bag and can be detached for easy use. It is a good size and is wipe clean - it doesn't have a fleece side like our other change mat - which I prefer. The strap is easily adjusted to fit the pram and is a good length for carrying over shoulder. I also love the little tags and the embroidered message "I'm on a mini mission" on the inside. The main part of the bag can be accessed from the top without having to flip open the bag - which is very handy when trying to get something in a hurry. The insulated bottle holder on the side allows quick access to bottles.
Would highly recommend this bag and the only reason it didn't get 5 stars was for the slightly disappointing lack of room for personal stuff and the small mobile phone holder.
