590 fits 750
I really like using Fidlock water bottles and was disappointed they don’t make a thermo sleeve for my 750ml. I really wanted a neoprene sleeve to keep water cold longer and prevent dripping condensation. I ended up getting the 590ml bottle so I could get the 590ml sleeve. Turns out the 590 sleeve fits the 750. Might even fit better (really snug). I imagine the sleeve will stretch if I keep it on the 750 so I’m not keeping it there. But interesting to know it does fit the 750. Keep another 590 thermo sleeve in mind if you ever need to buy me something 😀

Thermo Sleeve was Great Idea
Great idea making a thermo sleeve. I bought one for each of my bottles (3). It fits great and keeps my drink cool. I have yet to use it on a 100* day.
I hope to see one made for the 800. I use the 600 for now, it's a little small but it still works. Thanks for making a great product.
