About Iron Flask

At Iron Flask, sustainability is our jam. In addition to our sustainable water bottle selection, we’re excited to offer a range of tumbler cups in a variety of sizes and colors, specially designed for active lifestyles. Our classic tumblers also include stainless steel straws, plastic straws, and cleaning brushes to keep your tumbler squeaky clean. Enjoy all your favorite beverages on the go while reducing plastic waste.

Vacuum-Insulated Tumblers

Our tumbler cups feature double-walled vacuum insulation, meaning the exterior stays dry and never sweats. And whether you're drinking piping hot or icy cold drinks, you’ll always enjoy them at just the right temperature. Our 16 oz tumblers cool drinks for 12 hours and keep them hot for up to three hours, while the 24 oz and 32 oz tumblers keep drinks cold up to 16 hours and hot up to four hours.

Stainless Steel Tumblers

What better water bottle material than stainless steel? There’s never any flavor transfer, it’s tough enough to take a beating on any adventure while maintaining a polished, just-like-new look—and it’ll never rust. Plus, compared to plastic bottles, Iron Flask tumbler cups are reusable, non-toxic, and have 100% BPA-free lids, making them a healthier choice for you and the environment.

Tumbler Lids & Accessories

Our classic tumblers come with a press-in lid with a small opening that’s perfect for safe-and-steady access to your favorite drink.

Tumbler Warranty

At Iron Flask, we love our customers. Yeah, we said it: We love you. And that’s why customer service is our #1 priority. We believe in the quality and durability of our products, a testament to our lifetime warranty against manufacturer defects and a 100% satisfaction guarantee.
