If it ain’t broke, don’t fix it, right? Maybe under certain conditions, but when it comes to our products, we’re always working to make them better for you. Here are some of the improvements you’ll see in the Bison GEN2 stainless steel drinkware.

Bison leakproof lids

New lids with leak proof design

The new lids on Bison’s tumblers screw on to prevent leaks and have a flip-top lid for the same reason. The last thing you need when you’re driving down a bumpy road is for your coffee or iced tea to slosh out and make a mess in the floorboard. Heck, even turning corners with a full tumbler could cause a spill unless you have a GEN2 tumbler. Leakproof lids are improvement number one.

Bison tumblers sizes

Bigger and smaller sizes

Think of them as Papa Bear, Mama Bear, and Baby Bear. One of the new GEN2 tumbler sizes is bound to be “just right” for your beverage of choice. We added two ounces each to our old 20- and 30-ounce tumblers, giving you just a bit more space for thirst quenching at 22 ounces and 32 ounces. We also introduced a new, smaller size. Bison’s GEN2 12-ounce tumbler is the perfect size for cocktails or whiskey. Why should coffee get all the attention?

Bison stainless steel drinkware

Better grip

Wet or sweaty hands and condensation make it tough to grip any drink. Bison’s GEN2 tumblers are not only powder-coated for added insulation (eliminating condensation) and easier grip, they also have ridges to give your hands a little extra traction when you need it most. At Bison, we don’t just help you keep your cool; we help you get a grip. We’re chill like that.


Some things never change

Don’t worry. We didn’t change everything. As much as we value improvement, we also value dependability. The best things about the tumblers haven’t changed. GEN2 tumblers are still constructed of stainless steel for durability in even the most rough and tumble (see what we did there?) environment. They still have the same double wall vacuum insulation to keep your drinks hot or cold longer than you thought possible regardless of the external temperature. And our tumblers are still backed by a 5-year warranty.

All the quality you’ve come to expect from Bison stayed put. Oh, the tumblers will still fit most cup holders, too. We know better than to mess with that feature.

The GEN2 tumblers maintain our tradition of quality while upgrading things that make your life easier. Life keeps moving, and we want to be right there beside you, working hard and playing harder. Get your new tumbler today!
