This 1-litre black and silver seatpack is completely waterproof, with welded seams and a roll-top closure.
To ensure it doesn’t unwind and spit your tools out, Topeak have taken a belt-and-braces approach: the Wedge closes with Velcro before being rolled, and the ends clip into fasteners halfway down each side.
There’s a tab for a blinky LED light and the DryBag ﬁxes to your bike with a quick-release bracket on the saddle rails.
That’s its only weakness – the way too short, too ﬂat bracket only just ﬁts onto the saddle rails. But the bag itself is great, and there’s also a strap-attaching version.
