Does the trick! We got this for my son who has a bottle with the narrow straws. Maybe they would work with the bite valve that my other kid has too! Haven't tried.

The bit valves and straws are the smaller diameter and work great with all the kids water bottles and are very easy to clean. Don't bother with Amazon they still sell "new" bottles with the wider diameter straws which with much muscle will fit but come out of the bite valves easily. Camelbak easy shopping and shipping! My grandson loves his water bottles which are a smaller version of Grammies!

This nation has become a throw away society. We need more products that can be fixed or designed to have parts replaced. My son chewed the silicone straw til it broke though still usable (this was a long process from preschool all the way through 2nd grade). This replacement prevented the bottle from going into landfill. Shipping was super fast, straw is made long to fit bigger bottle, we just have to cut it to fit ours. Great quality silicone. Thank you camelback

Easy to order, quick shipping.

Worked great to replace the valves my toddler had been so hard on. Love having this option rather than have to buy all new bottles.
