Vacuum Insulated Flasks

Made to be your go-to accessory whether you are headed to the office or out for a hike. Our 18/8 stainless steel flasks use 25% thicker steel than standard to ensure they are built to last and tough enough for any adventure. The 100% leak proof lids and handy handles make them easy to carry with you.

Triple layer vacuum insulation keeps your hot drinks hot and cold drinks cold for hours, helping you stay happy and hydrated whether at the gym, at the office or in the great outdoors. You can even personalise your Ohelo flask to make it truly unique.

Not all stainless steel flasks are tough enough to withstand the harsh conditions of a dishwasher. Ours are.

Say Ohelo to thermal flasks that are easy to clean. After all, life is hard enough without having to struggle to keep your vacuum flask clean.

Did you know that almost all insulated steel flasks still contain toxic lead? A material banned from electronics and personal use is still standard for use in drinks flasks. Lead is toxic to people and the environment. Ohelo insulated flasks are all Lead Free.

All Ohelo flasks are BPA free. We go one step further and ensure they are BPS and BPF free too. These bisphenols are commonly used as replacements to BPA, but scientific studies have shown them to have the same hormone mimicking properties as BPA.  

Say Ohelo to lead free vacuum flasks. Say Ohelo to BPA free flasks that are also BPS free and BPF free. Say Ohelo to thermos flasks that are safer for you, our makers and the planet.

Ohelo flasks are made to be a true sustainable alternative to single use plastics. Being a reusable drinks flask is just the first step. Sustainability is key to all our business choices – from supply chain to distribution - to ensure our products are ethically made in a responsible way from safer materials.

Our sustainable practices are wide ranging: from on-site solar farms at both our manufacturer and distribution site to our use of plastic free recycled and recyclable packaging. From ensuring worker’s rights and wellbeing are protected to using endlessly recyclable stainless steel in all our flasks. From choosing to be lead free when most insulated flask brands still use toxic lead to donating a % of profits to charity. 

We hold independent international audits to show our ethical manufacturing practices as well as a range of certifications for our manufacturer.

Every time you use your Ohelo flask you can be happy knowing that 5% of the profits have gone to sustainable organisations that are making the world a better place. We are proud to support Surfers Against Sewage in their fight against plastic pollution and their bid to clean up our seas. We also support smaller, lesser known charities who all have great causes.
