The 20-ounce Activate Shaker Bottle from Stanley keeps your drink cold for hours, thanks to double-wall vacuum insulation. A rounded interior makes mixing and cleaning easy, while the fast flow spout provides a better sip. The inside is stamped with measurement lines and includes a removable strainer. The base storage container and the soft, easy-grip handle are great for on the go. And with a leakproof Tritan lid, it’s ready to toss in your bag. Hand wash recommended.
