KLEIN TOOLS 20 oz Stainless Steel Tumbler — Insulated Double-Wall, Flip-Top Lid, Textured Silicone Sleeve

The Klein Tools 55580 is a 20-ounce double-wall vacuum insulated stainless steel tumbler with a flip-top lid, textured silicone sleeve, and removable magnetic lanyard for secure hands-free placement.

Built for jobsite conditions, this tumbler combines thermal performance with practical features that make it easy to use while wearing gloves, carry securely, and reduce spills. The 20 oz capacity fits most cup holders, and the construction uses food-grade, BPA-free materials. Klein Tools designed the lid and sleeve to prioritize grip and access during long days where a durable drink container matters.

How long will the tumbler keep drinks hot or cold?

The double-wall vacuum insulation slows heat transfer to maintain beverage temperature for hours. You can expect cold drinks to stay chilled significantly longer and hot beverages to remain warm for several hours, depending on ambient conditions and initial liquid temperature.

• Cold retention: up to about 12 hours under typical conditions
• Hot retention: around 4 hours for still-warm results
• Stainless steel interior resists flavor transfer and staining

What makes the lid and grip suitable for worksite use?

The lid features a double-thread design so it’s quick to twist on or off even with gloves. A flip-top closes to form a spill-resistant seal, while the textured silicone sleeve improves handling on slick surfaces or when wearing protective gloves.

• Double-thread lid simplifies opening with bulky gloves
• Flip-top locks to reduce accidental spills during movement
• Textured silicone sleeve provides reliable slip resistance

Can the tumbler attach to metal surfaces or be transported easily?

Yes — the tumbler includes a removable rare-earth magnetic lanyard that secures it to ferromagnetic surfaces for temporary hands-free staging. A slip-resistant bottom pad also helps keep the tumbler steady when set on workbenches, truck beds, or tool carts.

• Removable magnetic lanyard for attachment to steel surfaces
• Slip-resistant base reduces sliding on uneven or oily surfaces
• 20 oz size balances capacity and portability for most vehicles

How safe and durable is the construction?

The tumbler uses food-grade, BPA-free materials and stainless steel that resists dents and corrosion during everyday jobsite use. Its outer sleeve and bottom pad defend against impact and slipping while preserving the inner thermal structure.

• Food-grade stainless steel interior and exterior surfaces
• BPA-free components for drinking safety
• Durable sleeve and pad protect against drops and abrasion

Who is this for: Tradespeople and outdoor enthusiasts who need a rugged, thermally effective drinking container that performs with gloves, stays put on metal surfaces, and minimizes spills during transport. It’s well suited for electricians, plumbers, construction crews, mechanics, and anyone who values a heavy-duty, no-nonsense tumbler on the move.
