A bottle with a straw rarely leaks where you would look. It weeps around the straw into the bag, and you find out when you take the bag off.
What Are the Key Features of This 1 L Bottle's Three-Point Leak-Proof Seal?
Three sealing points: the lid thread, the straw seat and the cover over the mouthpiece. A straw bottle has more places to fail than a screw cap, so leak proof counts for more here.
The straw is the wettest part, and it is plastic like everything around it: one family of material through the whole assembly, so there is no glued joint or metal component sitting permanently in water.
300 g empty: light enough that the hinge and the lock are never loaded past what they were moulded for, and that joint is what decides how long a flip-top bottle stays usable.
Four stocked colours: Black, Green, Orange and Purple, all on the same body and the same lid assembly.
BPA free where it actually matters: the straw and the seat it sits in are the parts your mouth touches every time, and both are the same BPA-free plastic as the rest of the body.
Where Can You Use This Leak-Proof Sports Water Bottle?
In a gym bag between sets, lying on its side
In a rucksack pushed under a desk
In a car boot
In a school locker
On an office desk
Why Choose a Three-Point Seal Over a Single Screw-Cap Seal?
On a screw cap, leak proof is one seal: here it is three: the lid thread, the straw seat and the cover over the mouthpiece.
Each of the three fails differently: the lock pulls the cover down on all of them at once.
Leak proof: this is the one in the range where leak proof is a spec in its own right.
One family of material throughout: body, straw, seat and cover are all moulded plastic, so nothing glued or metal sits permanently in water.
