Whether you purchase the 60L or the 150L, you're going to get a huge, versatile duffel. The Rinotek is super tough material, which can take the stress of a good beating, adventure after adventure. I have the 60L which has lots of space to haul your abundance of ski gear or camping gear when you're car camping. The duffel has lockable zippers, backpack straps, two interior mesh pockets in the top flap. The lock loops at the top of the zippers are protected by a strip of velcro the width of the bag--many reviewers dislike this feature, I prefer it for the added protection. And, like many other reviewers, I do believe the bag would be somewhat better with compression straps inside. This bag is worth the money, especially on sale.
