Waterproof Dry Bag Backpack

I have been using the "Sealine" dry bags for many years. My ditch bag is a "See 5", which is clear vinyl with a 3 mm white scrim. Despite over 100,000 miles at sea and thousands of dinghy trips, it remains water tight. I have had to jerry rig the replacement clips which eventually broke. It is smaller than the one Brent cited. Mine is 15" high, 8" wide and 5" deep. (the other is 20 x 10.7 x 3.1 inches).

Mine has wide heat bonded seams, and despite the abuse, no evidence of any cuts or loss of water tight integrity. It only has a single strap for a shoulder carry, with no padding (I could put padding on it). I have a number of larger bags we have used thru the years, and all are still waterproof. I had a genuine Navy Seal pack at one time--it was huge, had 6 buckles and was fully waterproof. The back pack and gut straps were heavy duty webbing.

SeaLine back packs a sample.

My bag is closest to the current Sealine Ecosee--but has the scrim, which does re-inforce it more than the plain clear bag. The bag has a round bottom; I like the bags with round bottoms best.

If you don't need a clear bag, then I recommend the Baja dry bag in the Sealine group.

My largest bag is probably close to 150 liters--which will take sleeping bags, and most of the gear you would want for a week camping.

That is huge 11.5 ft by 24.5 ft :D (according to the 3 pic on amazon) . It appears highly rated, I am interested.

The seller gives dimensions of The dimensions of the bag are 20 x 10.7 x 3.1 inches
 
I've used a Cascade Design "Duluth Pack" since I lived in Duluth (just a coincidence) decades ago. I don't think I spent this much, but if I did, it has been worth it. It has put up with tons of abuse. Right now, all of my bedding (thermarest, comforter, etc.) are stored in it during the day. https://www.seallinegear.com/boundary-pack-10
I use it since I had it already. I don't really use the back pack straps that much anymore, so I'm not sure I'd pay extra for that now. A simple sling would be sufficient.

I just bought some more dry bags because most of the ones I had were custom shaped to fit into kayaks. I bought light weight and heavy weight depending on usage. Heavy weight:

Light weight:

The ones with windows are interesting, though probably not as durable. I have to put little tags on mine to remember what's in them (towels, socks, etc. https://www.amazon.com/KastKing-Waterpr ... +bag&psc=1

I'm not endorsing these particular ones. When I shopped, I found prices are all over the place because the sizes are hard to determine. Read the descriptions carefully.

Based on my kayaking experience, I tend to have my dry bags secured to the boat with carbiners. Even if tucked away somewhere aboard, should I be in a "sinking" situation, a dry bag that is secured to the boat provides a huge amount of floatation. I suppose it could also be disconnected and used for flotation. The pack that you showed would be like having two additional life jackets.

Another Sealine dry bag backpack user here. I have had mine for about 12 years, have used the heck out of it, and it just does what it is supposed to do. When we have traveled using the scoots as our only land vehicles, that dry bag would hold the better part of a week's worth of groceries. (35 liter)

When driving the commercial boats, it is what I carry that has my gear (and lunch) in it. A good piece of gear.
 
Agree, our old Sealine clear bags never wear out. But they are heavy and bulky if you just want to ferry groceries back to the boat in the rain. Try Matador 24 Rainfree backpacks for that. Packable to can size with adjustable shoulder straps, very well made, and don't take up room. Wouldn't bet my life on them, but very suitable if your cruising is always within 20 miles of a Wal-Mart or ice cream parlor. Not for Brent.
