SoftFlask™ Speed 500ml

The pinch-welded bottom really does make a difference—it slides into my vest pocket without any wrestling, even mid-run. The wide compatibility means it fits every pack I own, which is exactly what I needed for a backup bottle.

The pinch-welded bottom is a game changer—slides into my vest pocket so smoothly I don't have to wrestle with it mid-run. It's held up through a few muddy trail sessions without any leaks, which is exactly what I was hoping for.

I needed a flask that would fit my running vest without bulging, and this model slides right into the pocket with zero fuss. The bite valve delivers a good flow even when I’m moving fast, which makes a real difference on long runs.
