Perfect replacement for the screw top.
No leakage, great quality, cheaper than I expected and compliments well including the colour.
All you need to do is cut the internal plastic straw, fit, screw on and it’s good to go.
Recommended by a work colleague, now recommended by me.
Not 100% leak proof
Nice lid for the hydro flask standard mouth bottles if your at the gym . I found that at work the lid did leak a little if it fell on its side or was carried anything other than upright!
I also found that the top gets muck around the spout which was annoying after a couple of times! I am really not a fan of straw lids either and I think I could taste the plastic on occasion? I went back to the standard lid after a week so not really for me this one?
The fact that it’s not 100% leak proof was always on my mind too!
The O-ring is a bit big.
The O-ring is a bit too big for the flask. You can get the cap on, but it’s quite tight to remove. I just replaced the orange O-ring with the ring off my old cap.
very good
does leak at all sometimes if you fill your bottle too mich when you open it it might squirt up a bit but that’s the only difficult i’ve had with i
