Answer: The Nalgene On The Fly BPA-Free Water Bottle Replacement Cap is specifically designed to fit Nalgene's popular wide mouth bottles. However, it may not be compatible with all Nalgene bottles, particularly those with narrow mouths. If you have a Nalgene bottle with a wide mouth, this cap offers a perfect fit.

Question:
Can this cap fit other brands of water bottles?
Answer: The Nalgene On The Fly BPA-Free Water Bottle Replacement Cap is optimized for Nalgene wide mouth bottles.

Question:
Is the Nalgene On The Fly cap designed for hot beverages?
Answer: Yes, the Nalgene On The Fly cap is suitable for both hot and cold beverages.

Nalgene Sports Water Bottle Accessories 341895 Editorial Review
The Nalgene On The Fly BPA-Free Water Bottle Replacement Cap fits all standard Nalgene bottles and CamelBak Eddy bottles. The cap is made of durable materials and features a leak-proof rubber stopper that works well even with thick liquids such as smoothies. Though the top may be initially difficult to close, it is worth it to have a secure and leak-free bottle. Unfortunately, some customers have reported issues with the latch breaking easily, which can be concerning.
