A product that's good to the last drop

__There is no denying the importance of staying hydrated on the golf course. With its new filtration water bottle (officially dubbed NSF/ANSI 53), Genuine Thermos is going for simplicity in design.

The 20-ounce, BPA-free water bottle ($25, available at Target) comes in four shades--clear, blue, pink and smoke--and has a locking push-button top that allows for one-handed operation. The filter is designed to reduce contaminants such as chloramine, atrazine and aesthetic chlorine. That way you no longer have to be concerned when filling up at a faucet or water cooler you come across at the course.

After filling the bottle up to 128 times, you should change the filter with

replacements sold separately; a two-pack costs $13.
