I discovered this amazing handlebar-mounted bag from Watershed Dry Bags just in time for a wet, early-spring bikepacking trip across a remote stretch of the Columbia Plateau. The McKenzie never bounced or hinted at coming loose thanks to the stretchy handlebar strap system that flexed to absorb the repeated blows from the trail without flopping all over the place. It kept my clothing, jacket, and electronics dry even in pounding rain and wind. The waterproof closure is like an industrial-strength Ziplock bag and the fabric stood up to scratchy desert brush and thorns. There are several compression straps for making sure everything will fit in the 15-liter bag and hard lash points too if needed. MSRP: $129. Drybags.com/product/mckenzie //
