SpeedCup™ 2-Pack

These things crush down to almost nothing when empty, so I just tuck them in my pack's hip belt pocket between water stops. The wide opening makes filling from a stream way easier than my old flasks, and they're super stable to grip even with wet hands.

Finally a soft flask that doesn't feel like a chore to carry. I love that it collapses down to almost nothing when empty, and the wide mouth makes filling it on the go so much easier.

I've been using these on every trail run since they arrived, and the collapsible design is genius—they flatten down to almost nothing in my pack once empty. The grip is solid even when my hands get sweaty, which was my main worry. Just wish they came in more color options.
