John N. ★★★★★ Oct 19, 2026

Fits into the front pocket of my pack so much easier than my old round bottle, and that wider base means it actually stands up on the trail when I set it down. The soft material is surprisingly durable too, I've shoved it in and out of my vest all week without any wear.

The 3D welded bottom is what sold me—it stands upright on my desk when I fill it at work, no more dripping mess. The wider shape is surprisingly comfortable to grip mid-run, and it slips into my pack pocket without any wrestling.

This fits my running vest way better than the skinny flasks I used before, mostly because the wider shape doesn't slide around when it's half empty. The soft material squishes down fine as I drink, and it hasn't leaked at the cap once.
