Have dropped these bottles in the past and they just cracked on the edges making the bottle unusable.
I'm hoping the TPU will give it some bounce without inner cracking to the bottle.
I haven't done any tests as I don't want my bottles to actually break but SOME is better than NONE. So I'm hoping this does provide the protection I made it for.
The lid slips over the top of the cap and clips to the base of it.
The base just slips on.
Tolerance is less than the circumference so the TPU stretch's to fit and hold snug.
