The HyperFlow cap adds fast, hassle-free access to your water. Rather than twisting a cap on and off, just bite down on the cap and drink. The cap's bite valve cleans easily and a simple twist of the stem ensures leak-free on-the-go hydration.
The Platypus HyperFlow Cap is compatible with all Platypus Soft Bottles, PlatyPlus Bottles and Hoser reservoirs (all sold separately).
- Upgrades any Platy bottle with high-flow, bite valve access
- Dual valve design easily rotates closed to prevent leaks
Dislikes: This cap is next to impossible to open. It is too hard to twist and leads to leaking.
