KeepCup Cold Cup Longplay Double Wall Glass Ice Coffee Tumbler - 16oz

Our review of the KeepCup Longplay Cold Cup finds it best suited to people who drink cold coffee, iced tea, matcha or smoothies at home or on short commutes and want a glass tumbler that looks and feels premium. The single biggest reason to buy is its tempered double-wall glass construction with a removable sleeve and spillproof lid, which keeps drinks cold while minimizing condensation on hands. In practice it balances style and function: it feels substantial, the 16oz capacity holds a generous iced brew, and the clear design makes layers and ice visually appealing.

Key Features

• Tempered double-wall glass: Provides a clean taste and visible presentation while adding thermal separation to keep cold drinks chilled longer.
• Removable clear sleeve: Protects hands from condensation and adds impact resistance without hiding the drink inside.
• Spillproof press-fit lid: A 50% recycled clear lid with a valve reduces accidental spills and secures the central straw.
• 12mm Boba straw included: A clear Tritan straw is wide enough for boba and thick ice, making the cup versatile for different cold beverages.
• Colour pop silicone band: Heat resistant band improves grip and adds a visual accent while being BPA/BPS free and non toxic.
• Fits most cup holders: The tapered base is designed to work with a wide range of car and bike cup holders.

Who It's For

The KeepCup Longplay Cold Cup is ideal for home baristas, cold brew fans, and anyone who prefers glass over plastic for taste and presentation. It suits users who value a spill-reducing lid and a wide straw for bubble tea or chunky iced drinks, and who appreciate a removable sleeve for easier drying and condensation control.

This is less suitable for people who need an ultra-durable travel mug for rough outdoor use or long journeys where a fully locking lid is required. Also consider a larger capacity tumbler if 16oz sometimes feels too small for your routine.
