The offers of diving backpack a large volume with good storage space, the only advantage. Unfortunately went on my first trip already a seam at the top handle and one of the small plastic mesh inserts in the lower part of the fin times already had a hole. So Exchanges and next trip. I have to say that the case brought at the airport 30kg on the scales. We were five weeks in the Philippines go and said goodbye to a seam after another, ie four times with Stern ran twisting and sew. The next problem was the many holes in the fabric. Front and rear, ie where the bearing surfaces are in transit had formed large holes (abraded and torn). That is the quality of the fabric so bad, I never expected. I had many years earlier a diving backpack by Suunto (favorite), unfortunately without wheels. Which is still in the basement and has not a single little hole. If man puts a finger into a crack or hole of the Red Line, man can without problems increase the hole that probably says it all. What brings super storage space when dissolving the part. Okay, the roles still rolling and the retractable handle still works. Conclusion: I can not recommend this backpack "AWAY"
