Recently just bought a Bivo Trio. I really cant believe how cold the water was kept.
It was a very warm day, into the low 30s…I used two bottles both filled with ice(1/3 to 1/2 full) and water. One was an Insulated Camelback Podium 24oz and the olther was a 21oz Bivo Trio.
Started with the Camelback and drank roughly half of it. Then I finished the Bivo bottle. Two hour ride. No ice left in the camelback. The Bivo still had a lot of ice left in it. Coldest water from the Bivo I have ever had while riding. Still very cold at the end of my two hour ride.
Cant say enough about it if you like your water cold.
