I can easily fit my 5d3 with a 24-70 as well as a 14mm UWA inside. Your SL1 is so much smaller you might be able to fit two spare lenses, or a lens cloth, spare batt, intervalometer, etc…
What a great film and adventure. Wow. The bag looks nice too.
I use a peli on a raft and I have used two different sizes of NRS Sea stow with a soft bag that looks a lot like the one MC is using above inside. The soft bag is shaped nearly the same but not waterproof.
While I have started to use some Watershed bags and they seem to work and my wife loves them, I am less convinced. The seals seem hard to do.
With the NRS Sea Stow ( which I believe was designed to slide into sea kayaks) the outer part is not rubberized but is more of a urethane nylon type surface which slide in and out of a kayak very easily. I would either slide the big one in behind the seat and it also had first aid, dry layer, extra rescue gear etc. Or the small one would clip in between my legs. I never had a leak on these bags ever. They are super easy to check for a seal as well. The hold their air pressure so you can actually check your seal. Not sure if that explains it well enough but I would regularly stuff a few grand worth of gear in there and never had a doubt. The day that I was paddling in someone else's raft at flood stage on the SF Payette and they decided to run the big hole river right was good test. The raft ended lodged upside down in the middle of dog leg on one of the only exposed rocks in the run. An hour later we got it off and the gear was fine.
The other thing that worries me about the watershed seal besides the cold and less than nimble fingers sometimes, is the few times I have been doing the photo thing and always ready for safety. When things have gone wrong I have gone from shooting pics to jumping in my boat in about 15 seconds. Literally shove the camera in the sea stow, three rolls on the seal and gone.
Not sure the availability of these anymore as the three I have are old. Like twenty years old. I still use two and have retired one to the tent bag. But they are tough.
That would also be the advantage of the small peli is that you are not futzing with a press together seal.
Of course in a raft I use a peli box in a couple of different sizes. The only peli failures I have seen are inadvertent seal dislodgement and when something gets in the seal like a camera strap or the small towel I always keep over the gear ( carry a zip lock if it gets too wet to put back in with the camera) to dry my hands a bit. I dodged a bullet on that one but if things went awry I would have lost all my gear.
After looking at sizes and ease of use I would get the one that gives you the most confidence in the seal when things go awry.
