Zéfal Z Adventure F10 bikepacking handlebar bag

Voluminous, leave a little margin to let hands pass on the handlebars but very practical once the support is installed. Really waterproof and resistant. Good quality/price ratio. (Translated review)

Well-thought-out spacious bag. Perfectly waterproof. Used on a not very wide road handlebar. I can't fully use the bag otherwise it becomes too wide, but there's plenty of room to put a lot of stuff inside. Be careful, on long rides, you sometimes need to tighten the straps (after a few hours and if the bag is a bit too heavy). But nothing bothersome. The attachment for an auxiliary light is practical. (Translated review)

Rather good, waterproof, and quite large for the place where it is located. Too full, it becomes difficult to position the hands at the bottom of the handlebar for better braking. So better to fill it to 3/4. But otherwise very satisfied (Translated review)

This bag is very practical for bikepacking, especially on a road bike: waterproof, possibility to remove just the red part while leaving the black part on the handlebars, size of the bag varying with the contents. One downside that Zefal needs to improve: the black straps loosen (with vibrations, especially if it rains), so the bag can end up rubbing against the wheel. It would be enough - in principle - to use straps like on the Zefal Adventure R11 for example. (Translated review)
