Pirani 16oz Insulated Tumbler — Slim Stackable Stainless Steel Cup, Slate, Triple Insulation

The Pirani 16oz Insulated Stackable Tumbler (Version 2.0) is a slim, triple-insulated stainless steel cup with a threaded, air-tight screw-on lid that keeps drinks cold 12+ hours and hot up to 6 hours while stacking for space-saving storage.

This upgraded 16 oz Pirani tumbler pairs the brand’s skinny-wall triple insulation with a new threaded lid system for improved leak resistance and performance with carbonated drinks and hot coffee. The pint-sized design stacks neatly for travel and storage, is dishwasher-safe, and swaps lids across the entire 2.0 lineup (10oz, 16oz, 26oz). Built to reduce single-use waste, it’s engineered for everyday carry, outdoor events, and grab-and-go routines.

How does the 2.0 screw-on lid improve daily use?

The threaded screw-on lid replaces the original press-fit design to create a more secure, air-tight seal that reduces spills and handles carbonation better. It’s simple to operate—twist 90 degrees to lock and twist off to open—and all 2.0 lids are interchangeable across sizes.

• Threaded seal improves leak resistance for travel and bags
• Handles carbonated beverages with less pressure release
• Quick twist locking action for fast access
• Cross-compatible with Pirani 2.0 10oz and 26oz tumblers

Will this tumbler keep my drink hot or cold for long?

Pirani’s skinny-wall triple insulation, plus an internal copper coating, boosts thermal retention so cold drinks stay chilly for 12+ hours and hot drinks stay warm for around 6 hours. The design also prevents external condensation, so the cup won’t sweat on warm days or surfaces.

• Triple insulation reduces heat transfer three ways
• Internal copper coating extends temperature retention by about 10–15%
• No-sweat exterior keeps surfaces dry
• Ideal for iced drinks, coffee, and mixed beverages

How compact and portable is the 16oz Pirani for storage and travel?

The 16 oz size is built to maximize capacity while remaining slim enough to fit most cup holders and backpacks. Its stackable geometry lets multiple tumblers nest together, saving cabinet and cooler space when not in use.

• Skinny profile fits standard vehicle cup holders
• Stackable design reduces storage footprint
• Lightweight stainless steel for easy carry
• Rolled lip for comfortable sipping on the go
