Hey all - we finally have a drop for Hydro Flask, linked above. We started with the 32 oz wide mouth, and will try to bring on some of the other top voted sizes and styles of Hydro Flask. Thanks for your patience in this poll and making this drop a success!
The 40oz and 27oz Klean Kanteens suggested by user ben_circa are NOT insulated. I own the 40oz bottle from this poll. It is definitely not insulated. Klean Kanteen only makes insulated bottles in 12, 16, and 20oz volumes. Of the bottles posted here, I also own the 18oz Hydro Flask and it is superb in every detail. HIGHLY recommended.
