SkyFlask™ — Made For Hydrogel

The narrow opening is a lifesaver—I can squeeze the 350ml into my race belt without wrestling with it like my old flask. The rigid top locks onto the gel system cleanly, so no drips mid-run. Honestly, this is the first handheld that feels like it was actually thought through.

Finally, a handheld flask that actually fits the Maurten gel system without a fight — the drawstring cinch holds everything snug. It feels balanced and doesn't bounce even when full.

Took this on a long training run and the 350ml capacity was just right for my gel mix. The narrow neck never leaked even when I shoved it deep in my pack, and it's way easier to clean than my old flask. Two runs in, no weird plastic taste either.
