Overview
Blend full-size smoothies, shakes, and lattes anywhere -- then keep them cold up to 20 hours or hot up to 4 hours in the same insulated 21oz stainless steel bottle. The 180W base crushes frozen fruit, ice, and protein into a smooth drink in about 20 seconds. Best of all, the blades now live in the lid instead of the bottom, so once you've blended, you twist off the top and you're left with a clean, cup-holder-friendly insulated water bottle.

The Redesign

We Moved The Blades To The Lid.

Every other portable blender hides its blades in the base -- so you're always drinking around them and scrubbing them out. Steel flips it. The blades live in the lid, so the moment you finish blending, you twist off the top and you're holding a clean, leak-free insulated water bottle. One vessel, blender to bottle, no compromise.

What's New

Blades In The Lid

Not the bottom. Twist off the top and your blender becomes a clean, leak-free insulated water bottle.

180W Pro Power

A high-torque motor at 17,000 RPM pulverizes ice, frozen fruit, and protein in about 20 seconds.

Hot & Cold Insulated

Double-wall stainless steel keeps drinks cold up to 20 hours or hot up to 4 -- same bottle, all day.

One bottle, endless possibilities
One Bottle. Endless Possibilities.

Blends Hot. Blends Cold. Blends Everything.

From morning smoothies to iced coffee, post-workout protein shakes to frozen mocktail slushies — the Steel handles it all with 180W of blending power and 17,000 RPM. Hot soups, cold protein blends, crushed ice drinks. If it goes in a cup, Steel can make it.

Two Tops, One Bottle

Swap In The Drink-Through Lid

Done blending? Twist off the blending top and swap on the drink lid — now Steel is a clean, leak-free bottle you can sip from on the go. No exposed blades, no mess, same insulated 21oz vessel.

Steel vs. A Regular Portable Blender

Most portable blenders are a plastic cup with blades in the bottom. Steel is built differently.
