THE BEST EVER!
I've used the 64oz Hydrojug for years, and was PUMPED to see 1st Phorm partner with them for this! I've been using my 64oz + a 40oz Stanley every day to hit my 100oz of water goal, and snagged this up as soon as I could. The biggest pro of this cup is the seal at the top that not only keeps whatever is inside cold, but also keeps it inside! There's no spilling, sloshing, dripping, etc! I highly suggest it!
