Good to know

The bag is not insulated, so it won't keep drinks cold, but it offers excellent protection and accessibility. The side mesh pocket is perfect for a small energy gel or a folded map. Installation is straightforward: wrap the three straps around your chosen tube and tighten – no tools needed. The drawstring closure allows one-hand operation, so you can hydrate without stopping.
