Yes! Thanks to our double-wall vacuum insulation, it keeps drinks cold for 24 hours and hot for 12. We’ve tested it ourselves—and made sure it performs better than most tumblers out there. Just make sure the lid is fully sealed!

Absolutely. Our tumbler is dual-temp engineered to handle piping hot coffee (up to 12 hours) and icy cold water (for 30+ hours). Unlike other brands, we don't hide fine print—you can safely enjoy both without compromising performance.

BriteLune tumblers feature a dual-locking mechanism that’s been drop-tested (yes, even on carpet!). Flip top lid is 100% leakproof, perfect for your bags. And even when you are using straw, the spill resistant-seal holds strong.

Never. BriteLune is made with premium food-grade 18/8 stainless steel—non-toxic, BPA-free, and rust-resistant. Plus, we coat the interior with a non-reactive finish so your drink stays pure, odor-free, and great-tasting all day.

My new favorite

I absolutely love this Tumblr. Trust me… I have bought all of the other brands that claim to be leak proof and they are not. When I found found this Tumblr. It was my hope that it would in fact be easier to open at the top without the seal, needing to be run under hot water. This Tumblr is everything I want and more. I love the dual spout access. I love the idea of a metal straw, which of course keeps everything nice and cold when drinking. The Tumblr stays extremely cold and the ice intact for hours and hours. My only wish was more variety of colors.

This has br one my favorite cup. And i hace them all. Stanley, rtic, Brumate, Hydro Flask and every off name brand on the market. The BriteLune keeps my drink cold and holds ice for 2 days and is not heavy like the other ones. The only thing indont like is the Pepto-Bismol pink. But that’s the only color that was available when I ordered.

Best tumbler I’ve ever owned!

I’ve tried them all—Stanley, BrüMate, Contigo—but BriteLune wins! It’s 100% leakproof (yes, actually!), and the 2-in-1 lid lets me switch between sipping and using a straw.

It keeps drinks cold for 30 hours, and the hot pink color is stunning—I get compliments everywhere! If you want a tumbler that’s stylish, practical, and spill-proof, this is it. Obsessed!
