The Rover Tumbler is designed to provide a superior drinking experience. The 100% leak-proof clear flip lid means you can relish every sip without worrying about spills or leaks. Thanks to the double-walled vacuum insulation, the Iron Flask Rover Tumblers remain sweat-free and effectively keep your drinks cold for up to 18 hours and hot for up to 4 hours. Crafted from premium 18/8 stainless steel, these tumblers are durable and free from metallic taste. That makes them the reliable, safe choice for enjoying your drinks on the go.
Stainless steel tumblers are highly durable and can withstand daily use without denting, cracking, or breaking. They resist impact, making them perfect for outdoor activities and on-the-go use. They also have excellent insulation properties. Iron Flask tumblers can keep your hot beverages hot for an extended period and cold beverages cold for hours. This feature means you can sip your favorite drinks at your desired temperature for longer.
Unlike plastic or glass containers, stainless steel tumblers do not retain or transfer flavors or odors, allowing you to enjoy a variety of beverages without worrying about any lingering taste or smell from previous uses. Stainless steel is a recyclable material, making stainless steel tumblers an environmentally friendly choice. Using them can reduce the consumption of single-use cups and contribute to minimizing plastic waste. Stainless steel is also a non-toxic material that does not leach harmful chemicals into your drinks.
If you're having trouble deciding between the Iron Flask Rover Tumbler, the Nomad Tumbler, and our Classic Tumbler, consider how you plan to use your new tumbler. If you're seeking a hydration solution for your workplace and prefer a tumbler that easily fits into most cupholders, the Classic Tumbler is the way to go. Our tumblers are worth trying for those who are frequently on the move and require a tumbler with a leak-proof lid. If you need a companion for your most rugged adventures, the Nomad Tumbler is your best bet, as it offers both a leak-proof lid and a splash-proof straw lid. Try all three – you’ll love all our stainless steel tumblers with straws!
Our tumblers are designed with double-walled vacuum insulation. This means your drinks will stay at the perfect temperature and the exterior of your tumbler will stay dry and never sweat. Keep your fav drinks cold for up to 20 hours and hot for up to five hours.
