Stainless straw for Hydroflask 32 oz wide mouth flex straw cap

I love the idea of this but the straws constantly fall out of the lids. We have three of these bottles that are used interchangeably and they all fall out regularly, so it’s not just one lid/straw combo that’s the issue. The stainless straw needs to be just a smudge bigger to fit in there snuggly. The other one I bought for a different style hydroflask works perfectly so it just seems to be this straw and lid combo, unfortunately! We will still be using them because the inconvenience of having to fix the straw multiple times a day is still better than microplastics!
