Big bottle probs are now solved! This spring I set a goal to start drinking 64oz of water a day and wow does it make a difference! I live to use my Nalgene bottles to easily track consumption but found I had nowhere to put them in my car. I would Just have to lay it sideways across my cup holders or set it in the passenger seat where it sometimes went for a ride when I hit the brakes. So much husband ordered this adjustable Car Cup Holder Expander. You simply set it in your cup holder and then twist the top part to adjust the bottom to fit to your actual cup holder snugly. It works great and is such a game changer! Here are the bottles that will fit: 32/40 oz Hydro Flasks 30/32/38/48 oz Nalgenes 20/26/30 oz Yeti Ramblers 40 oz Klean Kanteens 32/40 oz Camelbak #drinkwater #caraccesories #wellness #waterbottle #cupholder #adjustablecupholder #nalgene #camelbak #yeti #hydroflask #kleankanteen
