Bag purchase

Okay this might not be the best of titles, however it does describe the event.
Yesterday we purchased two bags. Both are in the form of wheeled back packs, which have their own removable day packs.
We moved to this type of bag, as opposed to other non backpack styles, due to modes of transport which will used this trip. Also the bags from our trip too years ago will be too large for this trip.
We are only going to be away for three weeks, and there will be more air travel, and less rail, we have to take less luggage.
We have to watch our weight limits. We will be limited to 23 kg for our Europe flights, while we have 33kg for our international sectors. The train travel will not be issue.
So as we progress there will be reports about the impressions of the bags.
So the two back packs are.

The first bag is the Caribee Sky Master 70 Wheeled Backpack. Purchased from the luggage professionals, Crows Nest, NSW

The Second is

The differences are:
is a side opening and the other is a top opening. They are different colours. There is 300 grams difference in their weight.

Both have removable day packs which we will use for the camera gear and iPads. So as time goes on we will make posts about the trip and the bags.
