These 10-ounce (300ml) replacement flasks come with a convenient push-pull cap and are BPA-free. They feature high-flow, soft-sip nozzles for maximum comfort and to help you drink more water when you need it most. The silicone grip caps are perfect for sweaty hands, ensuring a secure hold. These flasks are compatible with Nathan Speed 2, Trail Mix 4, and all QuickShots models.
Using these replacement flasks is easy. Just unscrew the cap of your Nathan hydration system and replace it with this new flask. Push the cap to open and pull it to close. When you're ready to drink, take a soft sip from the high - flow nozzle. To keep your flask in good condition, wash it regularly with mild soap and warm water. Make sure it's completely dry before storing it. Avoid using abrasive cleaners as they may damage the flask or the nozzles. Also, don't expose the flask to extreme temperatures for a long time.
