Leak-Proof Water Bottle with Straw
Leak-Proof Water Bottles with Straw
A water bottle is only as good as its seal. Every leak-proof water bottle with straw in the Proworks Switch range features a dual-sealed lid engineered to prevent spills, drips and leaks when the straw is closed. Whether it is tossed in a gym bag, dropped in a rucksack next to a laptop or thrown into a school bag, you can trust it to stay completely sealed. The leakproof design uses a silicone gasket around the lid plus a secondary seal on the straw mechanism, creating two barriers between your drink and the outside world. Inside, double-wall vacuum insulation keeps cold drinks chilled for 24 hours and hot drinks warm for 12 hours. Built from BPA-free 18/8 stainless steel with a powder-coated finish in over 10 colours, these bottles are available in 500ml and 1 litre capacities. Prices start from £25.
Key Features
- Dual-sealed lid: Silicone gasket plus straw seal for double leak protection.
- Tested for bags: Carry confidently next to electronics, books and clothing.
- Vacuum insulation: Cold for 24 hours, hot for 12 hours.
- One-hand flip straw: Easy to open and drink, easy to close and seal.
- BPA-free stainless steel: Food-grade 18/8 steel with no plastic lining.
- Condensation-free exterior: Double walls prevent sweat on the outside of the bottle.
How the Dual Seal Works
The first seal is a food-grade silicone ring that sits between the lid and the bottle neck. This creates an airtight closure every time you screw the lid on. The second seal is built into the flip straw mechanism itself: when the straw is pushed down, a silicone valve closes the drinking opening completely. Together, these two seals keep liquid locked inside even when the bottle is turned upside down or shaken. The result is a genuinely leakproof water bottle with straw that you can trust in any bag.

Frequently Asked Questions
Can I carry the bottle upside down in my bag?
Yes. When the straw is closed, the dual seal keeps the bottle completely leak-proof even when inverted.
Do the seals wear out over time?
The silicone seals are durable and designed for years of daily use. If they do eventually wear, replacement lids are available.
Is the bottle leak-proof with hot drinks too?
Yes. The seal works the same for hot and cold liquids. Just take care when opening the straw, as steam may escape.
