We compared two popular protein shaker bottles: the 32-ounce BlenderBottle Classic V2 and the 820ml Contigo Shake & Go.
What we looked at
Capacity, mixing ball or whisk, lid and leak-proofing, markings and storage, cleaning, and price.
The verdict
If you want the 316 stainless steel BlenderBall, ounce and millilitre markings, a flip cap with SpoutGuard and a limited lifetime warranty, the BlenderBottle Classic is the classic pick, at £19.82. If you would rather pay about £8 less for a 820ml bottle with a base that holds up to two servings of powder, a 100% leak-proof lid and a rotating carabiner handle, the Contigo Shake & Go is the value option.
A 32-ounce shaker with a stainless steel BlenderBall, SpoutGuard and a lifetime warranty, at £8 more.
