Double-wall insulated water bottles seem like they could be a simple product but there are very few out there that work robustly over time. Often seals will perish & not be able to be replaced or they become persistently dirty and cannot be successfully cleaned anymore.

The lid in this design features a single finger opening with a lever operated bung & is made from recycled plastic with interchangeable parts. O-rings on the bung can be replaced easily if they wear down. When you remove the lid the wide opening means you can access the interior easily for cleaning. The body is powder coated double wall insulated Stainless Steel which is infinitely recyclable.
