The new Topeak FastFuel DryBag top tube bag promises waterproof storage with a hard-shell design to keep its shape. What do you think?

More news from Eurobike 2017. Topeak’s sleek “FastFuel Tri” has evolved into the FastFuel DryBag, a 0.8 liter (50 cubic inches) waterproof top tube bag featuring a sonically welded DryBag design and waterproof zipper to keep contents protected from the elements. Constructed with a hard shell, Topeak claims the FastFuel DryBag keeps its shape “to prevent any leg contact”. It’s definitely a different and interesting prospect for weather sensitive electronics and such. For comparison, it weighs about the same as Revelate’s 65 cubic inch MagTank.

It’s also worth noting that the top-tube strap can be moved along several rubber reinforced daisy chains on the bottom of the bag (see below). There are a few additional photos on this Instagram story as well.
