Bivo

Bivo make the only stainless bottles that flow (no suction needed).
The Bivo patented Sports Flow nozzle uses a straw for air in-take that allows a nice full flow of water simply by tipping back the bottle.
Both insulated or non-insulated are available (2 sizes each).
The colored bottle have a silicone non-slip coating.
We recommend nylon bottle cages to keep them looking good over the years (not necessary, but an easy way to minimize wear of any bottle).
