I have bought a bag of Crete polyster 67cm slider bag, Product description and dimensions are accurate. Great quality check-in bag. I was looking for a medium sized bag to carry for week long trips. I looked through all the options available online and after almost a week of going through reviews, finally decided to go for this product. Quite spacious and looks very smart and sturdy. The wheels are very smooth and glide effortlessly even when the bag is packed to full capacity. But it is not water proof, but Great value for money!
