BOB Waterproof Dry Sak for Yak and Ibex Bike Trailers, Yellow

Very spacious, rainproof bag for your one wheeled trailer. Keep thing nicely secured when you roll top closure firmly. The side cleats are a little bit cumbersome when the bag is filled hard things. Soft clothes etc may get compressed to give you more room to reach the cleats but something like a cooler for example may quickly turn cleats unaccessible. Also I have concerns that the handles are strong enough to carry al the luggage that are on the heavy side. A full cooler, a BBQ, a vacuum bottle, etc are too heavy for these handles. I always place the bag in the trailer first, then I fill it up. I wish there would be cord to pass underneath of the bag to support the attachment points. I also have a smaller waterproof bag that I use it when I don't need to carry that much of things.

I bought my BOB back in 2011 and I'd say it has about 6000 miles on it, I've finally worn out the Dry Sak it came with with only a couple small leaks. I used it for everything including loading it full of heavy groceries and hauling it up a flight of stairs to my apartment. I see a lot of old BOB's out there without the bag and I just don't get that. The quality of this thing is so great and it is perfectly waterproof and it lasts so long, why would you live without it? Load it up with 50+ pounds of groceries and haul it up the stairs like I do all you want and it'll last years. Or load it with change of clothes, lunch, and tools and haul it to work, it'll take it.

The sak does work very well. Keeps your items dry. However, the clips on the sides that keep the tip flaps down, they are so inconvenient to reach when on a burley flatbed cart or even the Bob trailer. The bag virtually sits on its own clips. You have to go fishing to find them each time. Otherwise the bag is pretty darn good. The items don't COOK like in other waterproof bags in the sun.

I recently purchased the Bob Dry Sak to do some Bikepacking. I do not have a Bob Trailer but I made an Extension for my rear Bike rack and lashed the Bob Dry Dak onto it with some bungee cords. It worked perfect. The Dry Sak is large and held my tent, sleeping bag, sleeping pad, stove, clothes, foods, etc and I only used about half the room. I did not encounter any rainy weather but I would not have been worried because everything would have been dry in that Sak. If you need something big, heavy duty and waterproof, the Bob Dry Sak is for you.

I use this in my winter gear sled, and for a catch-all when rafting white water! Wouldn't be sound if totally submerged for any length of time, but fends off the rain, snow and errant wave. Very well-made, I've had one of these for 4 years now, and holding up much better than my traditional dry-bags. The volume and access is great, Will hold my tent, two pads and two sleeping bags, plus miscellaneous stuff.

Used the bag while biking the Pittsburg to DC bike route. Very sturdy and easy to pack and unpack.Love the comfort of it's fit into the BOB trailer.

The BOB Dry Sak works well even though the price seems high until you use it and it works!!!! With lots of room in the bag it makes the trailer much easier to use. I recommend it.

Awesome bag!

Works great for the bob trailer and can work(ish) as a dry bag in the canoe or on the deck of the kayak. Well designed and durable.
