Toute la famille est équipée de la gourde öko. Elle nous suit partout tous les jours : vacances, école , travail, ...

It's really great to go hiking without having to carry a lot of water and to be able to safely drink the fresh, invigorating water from the streams

I'm really happy with how it works, and especially with being able to drink clean water free of microplastics

This filter is excellent quality, and I love the color—I’d recommend it without hesitation.

I had barely ordered the pipette when it arrived. Just enough time to clean the first one! Great, thanks OKO

I've been using OKO since 2024 on my hikes
With the filters, I can safely fill my 1-liter water bottle anywhere—whether it's a river, a small stream, or a water source
I've never had any problems from the water I've drunk

I’ve been using this water bottle for several years now, as has my partner, to whom I gave it as a gift. We use it every day, which is why I bought a replacement mouthpiece for his—the original one had worn out because he tends to rough it up in his car...

The replacement filter is easy to install and just as effective as ever! Get one when you buy your water bottle so you always have a spare on hand—plus, it’s a better deal!

This water bottle is perfect for us since we travel abroad often, and especially for hiking—it lets us drink any water we find along the way

I'm thrilled with my purchase; I use the water bottle every day, and I love that it filters water instantly. I highly recommend this product!

Perfect for my mountain trip and my endurance training

I'm so thrilled to be able to drink water that doesn't smell like chlorine and tastes great! It's such a relief to have discovered this tap water filtration system! 🤩

Thank you

Really happy about the GR20

From the GR 20 to my water tap, my eco-friendly water bottle has been with me everywhere 😀💦
