A strong choice for riders tackling long, hot or remote rides who want more water between refills and have room for a large bottle.
When your ride takes you beyond reliable refill points, the ZEFAL Magnum gives you 975 ml / 33 oz of capacity to keep drinking for longer. At 85 g, it adds useful water volume without becoming unnecessarily heavy, making it a practical choice for hot-weather riding, endurance routes and bikepacking.
The Soft-Cap uses a food-grade silicone valve for comfortable, controlled drinking and a secure seal when closed. A wide mouth makes filling and cleaning straightforward, while the central narrowing improves grip and helps the bottle stay positioned in a compatible cage. The polypropylene body is odourless and BPA-free.
The Magnum fits most ZEFAL and other-brand bottle cages, but its 76 mm diameter means it may be too wide for some closed cages. We recommend an open cage such as the ZEFAL Pulse B2; it is not compatible with the Pulse A2 or Pulse Full Alu. The bottle and cap are dishwasher safe, and the bottle, cap and nozzle can be separated for appropriate recycling.
