From The Manufacturer

3 Liter (100oz), 100% odorless, tasteless, BPA- Free EVA material. Might be the most rigid hydration bladder on the market: 0.6mm extra thick liner is pressure-tolerant and wear-proof; double soldering sealing side technique has greatly improved durability. Double opening design. As the most popular design for high end hydration systems in recent years, this allows you to refill in any condition. High flow, auto-lock mouthpiece to prevent leaking and comes with dust cover. Insulated hose for better protection and help keep water cool/warm. Self-lock hose connector socket allows you to remove the hose quickly without any leaking. To avoid potential leaking, the screw cap should be securely closed as tight as possible! Twist the lid clockwise to fasten it tightly until the lid can not move any further under force! Please do not hesitate to mail us first if there is any issue about the product.
