Van Helix thay thế hệ thống hydrat hóa

Took it on a long trail run and barely had to bite down to get a good gulp—the minimal bite force is real. The retreat spring sealing means no drips in my pack, which I can't say for my old valve.

The 360-degree shape is the standout—I can bite down at any angle while riding and still get a full gulp without adjusting the mouthpiece. The retreat spring sealing also clicks shut cleanly with no drips when I tuck it away.

I wasn't expecting much from a valve, but this thing actually delivers. The retreat spring mechanism seals tight when I stop drinking, so there's zero dripping in my pack, and the low bite force makes it easy to sip even when I'm breathing hard on a climb.
