Review on 🌬️ High-Flow Helix Valve Kit for Outdoor Use - Soft-Bite Full Flow Bite Valve - QMT Quick Connect Mechanism Ensures Easy Connection - Dirt Shield Guards Against Dust and Pollution - Coyote Color Option by Jake Pavelko

A great mouthpiece if you like it really mouth-filling. The pacifier is big and I like it. I never knew what I was missing in a hydration system until I said suck on one of these. It revolves around the tube insert, which can be a bit annoying at times. But it's worth it if you really like big nipples on the water source. The lid is very secure, but can be a little annoying when removing it with one hand. But it covers the big nipple and keeps it clean. Definitely worth it if you have the Source Bladder system.
