One Green Bottle has been the official supplier for 3 Olympics and 2 Winter Olympics. Our commitment to finding the best sports bottles for athletes or anyone who requires hydration on-the-go has been recognised by the British Olympic Committee – who sent this testimonial after Tokyo:

“The heat of the Tokyo 2020 Olympic Games presented Team GB with a specific challenge to provide an insulated water bottle that kept drinks cold for athletes in the hot and humid climate. Onegreenbottle supplied Team GB with a branded stainless steel bottle with a sports cap which performed well under these intense conditions and undoubtedly helped give Team GB a performance advantage”    British Olympic Committee 2020

The Best Water Bottle for Sports – Olympic Water Bottles
Why are water bottles so important for sports?

A sports bottle is crucial for hydration, boosting performance, and ensuring health during activity by providing easy access to water, preventing dehydration (which causes cramps, fatigue, and poor focus). Reusable bottles also offer environmental benefits by reducing single-use plastic waste, while insulated options keep drinks optimally cold or hot, and durable designs offer convenience and safety.

Key Benefits:
Prevents Dehydration

Replenish fluids lost through sweat. This is crucial for maintaining blood volume, regulating body temperature, and preventing dizziness, headaches, and heat exhaustion.

Enhance Performance & Focus

Good hydration supports energy levels, endurance, muscle function, and concentration, allowing for better workouts and quicker reactions.

Temperature Control

Insulated bottles keep water refreshingly cold or even warm for hours, making them ideal for any climate.

Convenient & Durable
Built to handle intense activity, these bottles have leak-proof sports caps. They offer a fast and steady flow. The easy-to-use flip-up cap and internal straw make drinking simple. Built-in carrying handles for easy transport. Designed for active use.

Eco-Friendly

Reusable bottles significantly cut down on single-use plastic bottle waste, offering a sustainable alternative.

Safety Tested Guaranteed

Why should I buy a onegreenbottle when I can get a stainless steel water bottle for less money on Amazon or at any store? Our bottles pass higher than required safety standards. Bottles sold in supermarkets must meet REACH standards. These standards list chemicals that should not be in the product. However, these standards do not cover the harmful plastic chemicals that are outlawed in other countries. botl bottles go through strict safety tests. They are certified free from BPA, BPS, BPF and other phthalates. They also do not contain lead or other contaminants. Many of our competitors fail to meet these high standards – learn more

Why is BPA-free so important?

Bisphenol A or BPA is a chemical in plastics that has been linked to serious health problems. BPA is an endocrine-disrupting chemical, used to plasticise plastic.

Banned in some countries

Some countries, like Canada and France, have banned BPA. Other countries have also banned it in baby products. Because of this, some water bottles claim to be BPA Free. However, they may contain BPS, BPF or other similar chemicals which are very similar to BPA.

Is Bisphenol-S Safe?

Some experts have criticised plastic chemical companies for this ‘whack-a-mole’ approach to getting around governance. All onegreenbottle and BOTL products are free from BPA, BPS, and phthalates. This means they do not have any chemicals related to BPA. This is certified by LFGB including EU regulation 10/2011.

Convenience on the Go
A straw sports cap lets you sip without tilting the bottle — perfect for driving, walking, working out, or multitasking. You get instant hydration with one hand, no spills, no fuss.

Encourages More drinking, More Often
People tend to drink more water when it’s easier to access. The built-in straw makes it easy to take sips all day. This helps you stay hydrated without even thinking about it.

Great for Fitness and Sport
During workouts or sports, a tilt-and-pour bottle can slow you down or make a mess. Plus, who has time to unscrew a water bottle cap when there are important reps to do? Our straw sports caps are designed for quick, controlled sips without stopping the flow (literally).

Less lost caps, particularly for Kids
Straw caps are a game-changer for kids or anyone prone to taking off their cap and losing it.
