Source Outdoor Weave-Covered Helix Tube Kit Hydration Bladders - High-Flow Helix Bite Valve Delivers Full Flow with Just a Soft Bite - Weaved Cover Provides UV-Protection, Grey

The Helix Bite Valve from Source Outdoor features a rounded shape for easy drinking at any angle.

A retreat spring mechanism with a single-piece bite valve delivers a full flow with just a soft bite and a safety shutoff mechanism that won't leak under pressure or with prolonged use.
The 90-degree design allows the tube to be shorter, minimizing excess tubing around your chest and creating an ideal drinking angle. It also includes a Dirt-Shield protective cover that protects the valve from valve from dirt, sand, dust, mud, and other pollution.

This kit includes a co-extruded drinking tube with a Cool Weave cover that blocks UV light and insulates, keeping your water cool and inhibiting bacteria growth.
The tube's male connector is compatible with SQC (Source Quick Connect) and QMT (Quick Mate Technology) accessories.

Source has been a groundbreaker in hydration system technology and is also well known for its tactical gear and hiking sandals.
Tested in the most extreme conditions, hundreds of thousands of Source hydration systems are in use in the field.
