I have a drawer in my kitchen with approximately 1000 straws from various water bottles that you are welcome to come over and root through No, seriously, take 'em all.

Measure the hole and then go on azon and look for the right diameter / length of replacement straws.

I went from plastic to metal on some water bottles and it worked out fine.

There are loads of choices.

OP- thanks for your insight. FWIW, it was a gift, but of all the water bottes we have he likes it best for school, it's a good combination of size/ease of refilling/doesn't leak.

Thanks for whoever suggested the thermos straws!

I got some on Amazon but I don't remember what my search term was. You can try "pottery barn straw replacement" and see what comes up.

I would try Thermos brand. They make a larger kids size and they look similar. It works best to call Thermos customer service to order replacement parts.

DS has one of the taller Mackenzie pottery barn water bottles, like this:

Unfortunately, we lost the straw and PB doesn't offer replacements. We have some other silicone straws that are too narrow/loose. Does anyone know what brand straws would fit these? TIA!
