This is an excellent piece of kit which is well laid out and well built. The main bag can take up to a week’s worth of clothing with a little thought. I took mine away for 7 days in the USA and was perfect. The Rucksack can be attached or can slide over the handle for taking through the airport and onto the plane. The wheels are very smooth and the handle is a good length which takes the rucksack and a coat on top. I have yet to turn the whole bag into a rucksack but having played with it is quick and reasonably comfortable. A good bag which I would thoroughly recommend.
