BlenderBottle Classic Shaker Bottle 28oz - Clear/Black (Pack of 2) Review (2026)

What you get

This listing is a pack of two BlenderBottle Classic shaker bottles in the 28oz size, finished in clear and black. Each bottle uses BlenderBottle's original wire whisk design, a small stainless steel ball that sits loose inside the bottle and helps break up clumps of powder as you shake instead of leaving them stuck to the bottom or sides. The brand introduced this style of leak proof shaker back in 2004 and it remains the template most other shaker bottles on the market still copy today. A screw on lid with a flip top cap keeps the mouthpiece covered when the bottle is not in use, and a loop on top of the cap lets you clip the bottle to a bag, backpack strap or gym kit for carrying.

Fit for meal prep routines

Buying two bottles instead of one is the practical part of this listing for anyone building a meal prep and supplement routine. Protein shakes and pre workout drinks tend to get made at the same time every day, so having a spare bottle means one can sit in the dishwasher while the other is already loaded and ready for the next shake. The 28oz capacity is generous enough to mix a double scoop of powder with milk or water and still leave headroom to shake vigorously without spilling out of the flip cap, which is not always true of smaller 20oz shakers when you add a full scoop plus liquid.

Build and materials

Both bottles are made from BPA and phthalate free plastic, and both are dishwasher safe on the top rack, which matters for anyone rotating bottles daily rather than hand washing after every shake. Embossed markings on the side help with rough measuring of liquid as you fill the bottle, though they are not as precise as a dedicated measuring cup for exact recipes. The wide mouth opening makes it easy to drop in a scoop of powder, ice cubes or fruit without spilling around the rim, and the wire whisk ball is loose enough to rattle around freely and mix thoroughly rather than sitting stuck flat at the bottom of the bottle.

Where it falls short

The main trade off with this shaker is the clear half of the bottle. Colored supplements, especially greens powders or anything with added dye, can leave a visible tint behind after repeated use even with regular dishwasher cycles, and that tint does not always scrub out by hand. The bottle is also on the taller side at close to nine inches for the 28oz size, which means it may not slide into shorter cup holders in a car console or a gym bag side pocket built for standard water bottles. Neither issue affects how well the bottle actually mixes a shake, but both are worth knowing before committing to two bottles of the same clear finish.

Bottom line for buyers

For someone building a daily meal prep and supplement routine, this two pack solves the recurring problem of needing a shaker bottle ready at all times without hand washing between every single use. It is a straightforward, no frills product from the brand that popularized this bottle style, and the price for two bottles together is usually lower than buying two single 28oz bottles separately at full price. Anyone who drinks colored powders daily, such as greens blends or flavored pre workout, may prefer an opaque or all black version instead of this clear and black combination to avoid visible staining building up over months of regular use.
