The flip spout tops are replacements for the SUMMIT style bottles and will also fit the BOULDER bottle, PERK bottle (16 oz and 20 oz), FROST bottle, and SPLASH bottle to give you added value and versatility.
You can easily trim the straw to the length you need. We suggest you err on the side of cutting a little longer, as you can always trim more if needed. If you have an older bottle with 2013 stamped on the bottom or not dated, this top may not fit.
CAUTION: Spout could pose a choking hazard if chewed, bitten or comes off. If using for a kid's bottle, please check the spout every time it is used to make sure there are no rips, tears or damage and it is securely attached. DO NOT USE if there is any damage to the spout. NOTE: the spouts are NOT removable on these lids.
