Nalgene Cantene Wide Mouth Loop-Top 32oz Water Bottle Flexible

The flexibility of a soft flask, the reliability of a Nalgene — built for serious hydration on the trail.

The Nalgene Cantene Wide Mouth 32oz is a flexible, multilayer water bottle that stands up when full and folds or rolls flat when empty. The wide mouth fits ice cubes, is compatible with all major water filters, and the gusseted bottom keeps it stable on any surface. The leakproof loop-top cap is guaranteed not to fail.

Key Specs

• Construction: Multilayer flexible material
• Bottom: Gusseted for stand-up stability

Why It Works

Hard bottles take up space even when empty. The Cantene collapses down when you don't need the volume, making it ideal for ultralight packing or as a backup reservoir. The wide mouth means you can use it with a Sawyer, Katadyn, or most other filter systems without an adapter.

Ideal For

Backpackers, thru-hikers, ultralight packers, and anyone who wants a flexible water reservoir that doubles as a filter-compatible bottle.
