The Nutristrength Shaker in green is a convenient way to take your protein with you and make a shake when you need it most. It, of course, includes the standard wire ball. The Green Nutristrength Shaker holds up to 620 ml of your favourite natural Nutristrength protein drink. The ergonomic design and bright green colour means it really stands out, so you won't be losing your drink when you're at the gym or your local running club.
