I have three of these bags and two back packs made by overboard. Love them. I use this one as a tackle bag on my kayak. Liked the quality so much I bought larger ones for traveling.I absolutely love Overboard bags and this is my favorite one so far. I used the 30L backpack till I needed more room. This 60L duffel with backpack straps was the answer. Roll tops are great because if you dont fill the bag you can roll them down in size so the contents are still tightly packed and the bag dosent flop around. I use it for my latop case, work clipboard, cables, supplies, etc. I work offshore in the gulf of Mexico and these bags hold up to rough helicopter travel, bad weather, and heavy payloads (I pack 30 lbs of gear in my 60L bag and 44 lbs of gear in my 130L bag. I've tried other bags and returned them. Overboard all the way!Also... 2 zipper mesh pockets and 1 pvc material zipper pockets on the inside. A large velcro mesh pocket on the outside with a zippered pvc material behind it. The "wet gear" mesh pocker on the end for wet items or whatever. Comes with 2 removable shoulder straps.I really love this duffle bag, but the reason it doesn't get 5 stars is that if you load it down, the stitching on the back pack strap attachment points has started to pull out. This was with a full bag of clothing weighing 45 lbs. I emailed Overboard about the issue and they offered to replace the bag, but I didn't bother. They stated that 45lbs was about the limit of what they intended the straps for, and I can agree. They also stated, using the duffle bag hand straps, that they would handle the weight no problem and they were right. So only use the back pack straps if you don't have a lot of weight in the back. It is also very water proof and as advertised.I haven't used it yet, but I have used various dry bags on raft trips. It looks well designed, well made, and uses very rugged PVC fabric. The roll closure system should work well. As with all my dry bags, I will put my gear in a plastic bag inside the dry bag for an extra measure of protection.Bought this from my niece and she loves it. She is a sailor and she has to change from street wear to sail wear. It has lots of pockets and it is a combo backpack/duffel bag, which makes it easier for her to pull out items as she needs them.Perfect! Exactly what I was looking for. Great quality.So far this bag is awesome!I load it with clothes and toiletries when I rake my SXS on long rides or out in the boat to keep things dry and cleanGreat Bag,This bag is the perfect solution for my needs. I purchased this to hold my stuff on long bike trips. I was quite surprised to see that the quality was much more than expected. It seals well with additional straps to hold the fold in place. It also has many bungy or tie down loops to secure it to anything it is mounted too. Very please.....even if that's just the postman! Seriously, the read in this overboard waterproof carrier will grab attention and strangely (if found) it energies me?! Great for spontaneous shopping trips as well as carrying lots of equipment. Good purchase.Good size as handheld either on a day boat and/or on plane; works as a backpack with two straps; the sealing on the bag is quite long so you need to be careful that its sealed if you really need full waterproofness Perhaps one point - there are 2 back pack shoulder straps but no shoulder specific shoulder strap to use as duffel bag ...This is about the right size to put a camera bag, some shoes, swimming gear and a few phones/tablets in when going ashore in an inflatable. It fits under your arm using the handles over your shoulder, or you can use the two straps to make it a portable duffle. No water came in. You can leave it in the bottom of a dinghy, and the water there won't get in. A good bag.Bought this for a Camping trip where I travelled down a river on a SUP. (Stand up Paddle board) Bag was strapped to the surf board so tuck a good soaking from the river over the 3 day trip and kept the water out and all my kit dry. But... If this bag is truly 60 Litres I'll eat my hat! I have a 60 Litre canoe barrel and its holds a lot more then this bag which is ment to be the same size. If it did I would have given it 5 starsNot cheep, but having had it a while now, worth every penny. I've used it on the back of a mountain bike trailer and it kept
