I am comparing this to the Mamas and Papas Travel bag at approximately the same cost. Only down side: replace the draw string with a zipper.
It has a nice fabric that feels strong. I dont need carry handles as I have no intention of carrying my push chair anywhere other than on/off the luggage carousel. The bag is purely to keep it protected during the flight and transit. It folds out of its own little bag in seconds, pop it over the pram, pull the draw string and leave it at the gate for the crew to pop into the hold or pack it up before you leave home. A versatile Size: 120cm x 45cm x 35cm, with room to sneak in a couple of packs of nappies (no one at the checkin desk looks inside the bag and a pushchair is separate to your luggage allowance) There is a transparent tab to slot in your holiday/contact details and the flight luggage label could be looped into the draw string before it is pulled. I have been travelling with kids for 14 years now and have alot of long haul experience, this bag does the job!
Purchased for a Quinny zapp xtra as they do not produce a bag that fits the chassis and seat unit together.
