27 أونصة Classic مع غطاء Flip Seal Sport

Filled this with ice water before a hike and it was still cold-ish two hours in, which is about what I expected since it's single-wall and not insulated. The flip seal cap snaps shut tight enough that it hasn't leaked in my bag once.

I was skeptical about a steel bottle that isn't insulated, but it's so light I forget it's in my bag, and the flip seal cap snaps shut with a reassuring click every time. Perfect for tossing in a car cup holder or just carrying around the office all day.

The flip seal cap is genuinely leak-proof in my bag, and since it’s single-wall, the whole thing stays feathery even when full. I’ve been grabbing it for gym sessions and errands alike, and the wide mouth makes filling and chugging effortless.
