So..... 3 days in hot, humid, and sticky Cuba, and 1 day in hotter, humid-er, and stickier Panama. No matter when, no matter where - I always had ice cold water. Went through 4-5 liters per day.
Un. Freaking. Believable.
I didn't get the straw, so I only had the wide mouth. Yes, it sometimes spilled a bit while drinking, but honestly I didn't mind. It just cooled me off a bit
.
Hung if from my belt loop with a carabiner attached to the cover loop, worked like a charm.
And...
Am I gonna regret not getting one?
Yes, yes he did
