Owala Silicone Water Bottle Boot, Anti-Slip Protective Sleeve for Water Bottle, Protects FreeSip or Flip Stainless Steel Water Bottles, 24 Oz, Black

Sized for 24 oz stainless steel bottles, this Owala silicone boot wraps the base of a FreeSip or Flip bottle in a flexible protective layer. The moulded sleeve measures 3.13 inches wide by 2.71 inches high and weighs about 1.76 ounces, so it adds grip at the bottom of the bottle without changing how it sits in a hand or a cup holder.

Silicone cushions the base against knocks, taking the impact that would otherwise leave dents or scratches on the metal. The same material softens the sound of a bottle set down on a hard desk or table, and its textured surface resists sliding on smooth counters.

• Fits 24 oz Owala FreeSip and Flip stainless steel bottles, and also suits Owala 40 oz tumblers.
• Not made for tritan plastic bottles, or for 19 oz and 25 oz sizes.

One boot per pack in black, dishwasher safe, bottle sold separately.

To fit the boot, turn it inside out slightly at the rim, align it with the base of the bottle, then roll it down evenly so it sits flush without bunching. If it feels stiff at first, running it briefly under warm water softens the silicone enough to seat it cleanly. When removing the boot for washing, peel it from one side rather than pulling straight down, which makes it easier to separate from the metal without stretching the material out of shape. Both the boot and the bottle can go on the top rack of a dishwasher separately, which keeps residue from building up in the gap between the two.

This product suits people who carry their bottle in a bag alongside other items, since the silicone absorbs the minor impacts that happen when a bottle shifts against hard objects in transit. It also works well for anyone who sets a bottle down frequently on tile, glass, or polished wood, where bare stainless steel tends to skid or scratch the surface. When comparing silicone boots across brands, the key things to check are internal diameter and height, since even small differences in bottle base dimensions can cause a sleeve to ride up or fit too loosely to stay in place during normal use.
