GASP Shaker is extremely good for protein shakes, gainer shakes and even as a water bottle. The GASP shaker can hold up to 700 ml of liquid/powder mix and are clearly labelled for accurate measures.
It´s a new generation shaker with a twist top for best use! An enclosed screen mesh avoids lumps and you can shake and drink straight from the shaker. - A "must have" to gain muscle size!
