BBAIYULE Hydration Backpack Bladder 2 L, Running Bicycle MTB Hiking Small Men Women (Black (Upgrade the Blue Bladder)), 44cmx23cm

• 360 grams: light, small, strong and comfortable to wear. Whether running, biking, hiking, mountaineering or skiing, the extra weight on your back consumes only unnecessary energy, which is why we combine maximum comfort with minimal hydration backpacks.
• Air cushion: specially developed "air flow padding" air padding on the back, breathable and sweat-absorbing for maximum comfort in the back, shoulder and waist area. Adjustable waist belt and chest strap to ensure it does not wobble during exercise.
• Environmental protection: contains a 2L water bag, no BPA, made of food grade EVA material and can be filled with ice cubes. All you need to do is bite slightly into the hose when sucking in water. The water bag has passed a 100 kg pressure test and will not leak.
• Spacious: 1 large compartment that can hold 2L water bag. Two easy-access side pockets are enough to store mobile phones and other small items such as keys or wallet. The extra zip compartment on the back offers enough space to store energy food.
• After sales guarantee: 6L backpack, including 1 2L water bag; suitable for women, men and children; all BBAYULE products are free return and exchanged. If you are not satisfied, thank you for messaging by email.
