4L Hydration Water Bladder (135oz) – Heavy-Duty Large Reservoir, Wide-Mouth Easy-Fill, Leak-Proof Drinking Tube

• Large Capacity 4L Hydration Bladder: Designed for extended treks, this 135 oz. water reservoir holds up to twice the capacity of standard models — ideal for all-day adventures when water access is limited.
• Durable, Leakproof Construction: Made from heavy-gauge PEVA with reinforced seams to resist punctures and prevents leaks, even under rugged conditions.
• Fast-Disconnect Hose System: Hose clicks securely into place with a simple insert-and-lock mechanism; push-button quick release allows for clean detachment without drips. Auto-shutoff valve prevents leaking when the tube is detached.
• One-Hand Valve Control: Patented bite valve design features a push-rotation on/off system for reliable, one-handed use while hiking, biking, or climbing. Tethered dust cap keeps the mouthpiece clean and flicks open easily when you're ready to drink.
• Extra-Large Fill Cap: Oversized screw cap with integrated handle allows for fast and easy filling (even with ice!) and cleaning. Volume markings in 0.5L increments make it simple to monitor your remaining water supply.
