• Use with or without internal straw

You can use your onegreenbottle sports caps with or without their internal silicone straw. To use with the internal straw; drink from the bottle in the upright position – don’t tip it. If you use without the internal straw you tip to sip. If you choose not to use the internal straw supplied please keep it handy for use as a reusable straw. If you do use with the internal straw make sure you clean it regularly with a tiny brush or pipecleaner.

If you are having problems with not getting enough water through your sports cap please try the following things:

  1. If the internal straw is attached make sure you are not tipping the bottle
  2. If the internal straw is attached make sure it isn’t too long – trim to an angle so it doesn’t touch the base of the bottle
  3. Try using without the internal straw – make sure you tip to sip
  4. Still having issues – email us or give us a call we are always happy to help


Our bottles are made from 304 grade stainless steel which is the safest material around for drinks containers. Non-rusting, non leaching and toxin free, it ticks all the boxes and it won’t let you down. Its the Leo DiCaprio of metals.

Our caps are BPA/BPS free, which makes them better for you but a little bit more fragile. Treat me with the TLC I deserve (and supervise children who might be tempted to give my cap a chew!)

  • Leakproof when closed

We like to keep things tight here at OGB, so your bottle shouldn’t leak. If you’re having issues, make sure your valve is intact (you can find it under the folded down spout). If you need a new one we sell replacements, check them out below. And finally, make sure you screw your cap on properly *eye roll*.


We sell replacement seals and air valves in case yours go astray. If you are carrying your sports bottle in the bottom of a bag make sure it cannot accidentally open or position it upright in the bag OR invest in a screw cap

  • Leakproof when closed

Don’t be afraid to get your hands dirty! Our painted bottles could lose their good looks if they get put in the dishwasher. Oh, and make sure you drain your bottle upside down otherwise you could be smelling pretty pond-y when you open your bottle at work the next day…and no one wants to be THAT guy.

To get rid of smells, spots and stains, try these tips:

  1. Make a paste with baking powder and water
  2. Use a bottle brush and the paste and scrub all around the inside of the bottle.
  3. If you have a persistent smell – put a mixture of white vinegar and water 50:50 into your bottle and let it soak overnight
  4. Drain most of the water/vinegar mixture and add some baking powder, give another scrub, then rinse well!

Bosh, care instructions done.

Clean your spout and internal straw regularly. Invest in a teeny tiny brush or pipecleaners and clean through with warm soapy water. Rinse well and drain dry upright. Never remove the hard spout part and take care not to lose the air valve that sits underneath the folded down spout. We sell spare air valves and seals. Caps are happy in the top rack of the dishwasher but for best results use a brush
