Material18/8 stainless steel
The IRON °FLASK Co-Pilot is a 32oz double-wall vacuum-insulated tumbler designed for everyday portability. It keeps drinks cold for up to 20 hours and hot for up to 5 hours, powered by stainless-steel construction. The tumbler ships with two lids — a splash-proof straw lid and a leak-proof flip lid — giving users flexibility for different drinking scenarios.
Key features:
- 18/8 stainless steel, BPA-free and non-toxic
- Fits standard cup holders (compact, 5" × 5" base)
- Lightweight (0.33 lbs) for travel
- Wide mouth opening for easy hand-washing
- Rubber non-slip bottom for stability
The Co-Pilot sits in the mid-tier insulated-tumbler market — offering solid build and dual-lid versatility at an attractive price point (~$14–15 with Prime discount). It appeals to commuters and travelers who prioritize cup-holder fit and ease of cleaning over premium brand cachet. Not category-defining, but a reliable everyday option.
