It comprises of a plastic water bladder, accompanied by a flexible silicone feeder tube with a bite valve at the end. As for the Hydromax’s armored exterior pouch, it is attached with velcro to the back of the player’s shoulder pads. Located within the pouch is a wide, flat bladder, and such a shape goes a long way in dispersing impacts, while fitting in relatively unobtrusively under the player’s jersey. If you’re at the bottom of a pile, fret not – the bladder is capable of expanding up to eight times its normal size without bursting.
We do wonder how carrying the extra weight in water would affect the player’s speed and stamina throughout the game – maybe it isn’t such a good idea after all, but only time will tell whether this $49.99 purchase is well worth every penny or not.
