I have some hunting pack frames that I prefer to use for portages due to their comfort with a lot of weight on them. I just attach a large dry bag to the pack frame with some compression straps and grab-it for the bottom of the dry bag.

My issue is that the dry bags that are large enough for my trips end up being too tall to fit in the canoe sideways.

Are there any dry bags out there that are shaped more like the Duluth packs or Granite Gear packs; large capacity, but wide rather than a long, tall tube? I don't need shoulder straps or waist belt on the bag, but I guess I'd be ok either dealing with it or cutting off what I don't need.

I have one of these and it’s great. Can check to see if the dimensions are more what you’re looking for. Believe rutabaga sells them too.

Nope, there are not.

Two options to consider:

Eberlestock Element Dry Bag

Kuiu Karluk 3000

That’s as close as I’ve seen, but at only 70d I’d have to baby it pretty hard. I was hoping for more of an ultra durable dry sack.

I think the eberlestock is similar to what I have now. They function great, but I end up having to put them in the canoe the long way rather than short. The Kuiu is just a bit small for me. I try to hoof it and single portage with everything all at once.

Have you looked at the sea to summit big river dry bags? 420d and their 65L, while taller than wide, is listed at 28 inches tall which should fit sideways in a canoe without trouble.

Big river dry bags

I have a few of the 35L big river bags. They’re the perfect toughness to weight ratio. 65L would come close to handling all of my stuff for a trip, but not quite. My buddy and I prefer to single portage so the two packs + dry bag we bring end up pretty big.

Not a typical dry bag but, what about the Mustang Survival submersible deck bag? No belt or shoulder straps, but if your attaching it to a frame, it has d-rings. Deck bag

This is probably not what you are looking for because it would replace your current frame/drybag setup, but here goes. I have a KnuPack EZ-Tripper system that I want to sell. The description and photos are below.

Bag dimensions (approximate): 34" x 17" x 11" (HxWxD)

Bag: nylon dry bag with roll-down side entry; coated on the interior with polyurethane; feels like 1000 denier; top lifting handle; side compression straps can be used for lifting.

Frame: 31" x 15"; 1" diameter side tubes.

Shoulder straps: 0.5" thick; load lifters have 3 possible horizontal positions on the frame.

Hip belt: 1" thick with a 1.5" lumbar pad;

Frame’s back panel consists of a lightly padded, shaped panel above the lumbar position and a ventilated, vertically adjustable fabric panel.

Extras: 2 U-shaped canoe yoke portaging supports for the top of the frame; a quick-release strap to be used with paracord attached to bow and stern thwarts for balancing the canoe while portaging; a U-shaped frame extender with 3 positions; a bottom shelf for carrying oddly-shaped, heavy loads instead of the dry bag; 2 extra straps for odd loads; extra frame pins.

Total weight: 8.5 lbs without yoke carriers, extension frame, or bottom shelf.

Interesting. I hadn’t heard of those before. It’s just a bit small for what I need, but we’re getting closer and I have another google rabbit hole to go down.

As close to the 411 on the Knu-Pac EZ Tripper as you’re likely to get:

Anybody tried the Knupac system?

Why not use a Duluth bag and double line the interior with garbage bags?

Think this is what you are looking for:





Sea to Summit

NRS version

NRS

You've probably already thought of this, but what about two ~40-60L PVC (durable) dry bags strapped crosswise on your frame (one above the other as you're wearing it)?

Might give you the capacity you need while fitting in the canoe better than a single long/skinny dry bag?

NRS Tuff Sacks

As for me (I prefer a duluth pack), I would be tempted to try one of those Recreational Barrell Works liners shouldertripper mentioned, if it was available in silnylon.
