factory replacement, works perfect. The only thing that would improve it wold be for it to not break like the last one did... The covers for these bottles are not rated to drop onto concrete from waist height.

Great to have extra caps , if one is misplaced you can still use your bottle. These bottle are the greatest, saves on ice, fluid stay cold or hot much longer. Would recommend to everyone, great too keep one hydrated.

If you need this, you need this. My son has managed to break two already so I hope this one lasts awhile.
