Purchased four, three survived the first hike… One developed numerous pinhole leaks. Not ideal,But not sure was not user error. Good enough for the priceGreat quality and Price. Love the larger size. I was able to use this as my bear bag and it worked perfectly.Decent cheap dry bag, actually us this for extended trips as a trash bag, keeps smells down doesnt take on water and its cheap enough i dont feel to bad chucking it if it gets a bit nasty. I have not had any issues with it failing.The stuff sack on my sleeping bag tore and I needed a replacement. I calculated the size I needed based on the torn stuff sack. I laid it flat.I used 2 * pi * radius * radius * length to get the volume in square inches and then divded by 61 to give me Liters. To do this I measured the opening (aka the diameter) of the stuff sack while it was laid flat, divided it by 2 (to get the radius), squared that number, multiplied that by 2pi (3.14159 x 2) and then multiplying that by the length.Length of stuff sack = 16 inchesheight of stuff sack = 8 inchesVolumes = 2 * 3.14159 * 4 * 4 * 16 = 1608.5 cubic inches = 26.3 LObviously 26.3 is > 25L but I took a chance and with some extra stuffing I was able to get it to compress and fit in the bag. Should I have gotten a larger bag? Probably. Does it work and keep my bag protected from the elements? Absolutely. Comes in handy as I'm usually transporting the bag on/off a boat and one slip could ruin a trip.I like that it's coated with that sil nylon material (silicon coated nylon), so it's got great water resistance. I'd use this as a bear hang food bag, or else a clothing bag for backpacking. It's very lightweight and really can't beat it for the price.For the price, these can't be beat. Great lightweight dry bags that really do seal up well. At half the price of the other brands, these are perfect for ultralight backpackers who like to keep their packs organized and their gear water-proof. I haven't loaded gear up in one and submerged it yet, but for rain protection they do great. I even use a 25L one half-inflated with air as a camp pillow and it holds air all night. Just roll the top down at least 4 times and clip the ends shut and it's perfect as a pillow. Always good to have dual purposes when backpacking.These are thin dry bags so don't expect to jam them full of pointy items and expect them to last forever. These are great for keeping clothing and lighter items dry. Perfect for using as a food hanger up in a tree in bear country, too.Used this a few times now and really like it. its not the think material you can thow on fishhooks and expect not to rip but its good at keeping water out. It was a life saver on a rafting trip storing phones and valubles that otherwise would have been ruined. Its a great size and does compact down to be more convienient for smaller uses. its got a great seal and well worth the money for a first dry bag or something for moderate use. Heavy use and i would go for something thicker to last longer but this is working very well for me so far.We had purchased some 20L and 30L SealLine dry bags two years ago on Amazon, and we needed a few more for a trip on the Buffalo River in Arkansas. I saw these on Amazon, and asked my son if he wanted the 20L SealLine or the 25L Coghlans. He thought the extra 5L would be helpful, and the price was about half, so we ordered two.Good thing we did, because it took about two of these "25L" bags to equal the 20L SealLine. I'll try to post some pictures (hopefully, never done that before), but these bags are about 25 - 30% smaller than the 20L SealLines. And material/construction are nowhere near the SealLines. The Coghlans bags are very thin, like a cheap windbreaker, and the taping on the inside looks to be poorly done (again, I'll try to post pictures).In fairness, though, the bags kept things dry through four wet days canoeing. In the end, that's what its all about. But don't be fooled by the size -- when closed up, the 25L are small bags.This is listed as a "lightweight" bag and it's certainly not as sturdy as some of my other bags, but it was also a lot less expensive and it still worked well. Kept my stuff dry sitting in a flooded bulkhead for over an hour. It wasn't totally submerged, but it was floating around in some pretty deep water. If you don't abuse it, I think it will last just fine. Also strikes me as the ideal bag for lining the inside of another, non-water proof pack.I have 3 Coghlans Dry Bags now. 2 for clothes and 1 for food. These things are awesome for the price point as well as great durability. No issues with ANY of them yet.Left it outside for 12 hours in moderate rain and everything stay dried, even with a small pool of water on it. Though as it is really thin material I wouldnt feel confident leaving anything too important in without a secondary source of protection. Just incase it got a tear or hole you are unaware of (it doesn't seem hard)This bag is water resistant but not waterproof. Used this as my food bag while backpacking. Hung it in the tree and it rained overnight. Everything in it was wet.Using it as a replacement for my sleeping bag "Stuff" sack. My sleeping bag "sticks" to the inside of the bag, making "stuffing" a bit tricky. Otherwise, seems about right!
