Waterproof rear trunk bag recommendations - please give.

Got drenched the other night, and my bag got soaked. Stuff inside wet.
Anyone recommend a waterproof bag you like?

I am using Topeak racks and one of their regular bags, but will switch racking systems if something cooler comes along.

After the other night I was wondering why makers make anything but waterproof bags.

How much stuff do you need to carry? But the low cost option is to use one of those plastic shopping bags as a rain cover. Heck, depending on the size of your current bag, you might be able to just get by with using a shower cap.

ETA: If you really want to spend some coinage, check into Racktime, which is Ortlieb's 'economy' brand.

I carry mostly sundries on commutes:
iPhone, keys, reflective vest, small food container, etc.
But I think I'll go bigger, because there are times when I have needed to carry more.

Same reason they make bikes that have to be cleaned and lubed after a single ride in the rain -- most recreational cyclists avoid rain. Why pay for waterproofing they'll never use?

Depending on what I'm carrying, I like Ortlieb, Pelican cases, and Seattle Sports Aquaknot dry bag backpacks. Or a waterproof trailer if I'm really hauling a lot.

Carry a plastic garbage bag in the trunk; put everything in it and fold it over a couple of times if it starts raining.

Topeak makes a waterproof cover for their bags, some LBS will stock it or they order it for you.

Topeak makes waterproof covers for their bags, if LBS doesn't have it they can probably order one for you or just use a plastic bag for stuff inside or put over the bag.

Ortlieb makes nice rack bags in several sizes and colors if you want to go waterproof rather than covering your current bag.

Another option to consider (if you have the funds) is a Carradice bag.

+1

Ziplock or Glad make the best waterproof bags I've found. Don't spend money on a waterproof pannier or trunk bag. Plastic bags inside the pannier work the best.

If you want a waterproof rack bag, look at the Ortlieb Bike Box 2. It's not cheap but it is waterproof and the rack attachment is super solid. The Racktime bags aren't as expensive and they come with a rain cover. But they are made to fit on a Racktime Rack much like your Topeak is made for a specific rack. I have a couple of the Racktime bags and one of the Bike Boxes. I modified the Racktimes to fit on my Ortlieb mount by purchasing a basket adapter from Ortlieb. You only have to do a little surgery on the bag to get it to work. I actually like the Racktime bag a bit more for dry commuting because it has more volume.

As to why they don't make all rack bags (and panniers) as waterproof, look at the cost.

If your bag is a high dennier material, you might increase its water resistance by using a good fabric waterproofing material. I used it on my old specialized bags, and it didn't make them waterproof, but it would take a lot more of a soaking than without the stuff. 3M makes some, and you can usually find it in an outdoors store, or similar areas in even most grocery stores.

That wouldn't help with the zippers, that is where most water seepage will be.
