I absolutely love this tumbler I absolutely love this tumbler. It is very well made and completely leakproof, even when upside down. It is 94 degrees outside today and held my ice water perfectly the entire day. When I sucked the last drop of water out six hours after I got there ice was still plentiful in the cup.

Great product and great support Great product and great support. I have multiple Bison products and they work for me every bit as well as the "name brand" for a much lower price point. They are not cheap knock-offs, the quality is first-rate. I have had problems with a couple of orders over the past several years, and customer service has always been super responsive and helpful. This probably means more to me than the quality of the product does. Great service is hard to find and sure appreciate it when I do.

Bison 22oz coffee mug Love my Bison 22oz coffee mug it keeps my drink hot for far longer then needed and when my lid broke (because I muscled it to much) I was disappointed but I was relieved to find well priced replacements on their website. Low and behold within a few days my replacements arrived promptly.

Great customer service I received prompt attention from customer service "Brian" on a zipper warranty claim. He exceeded my expectations. Super fast shipping and turn around time. I received very prompt emails about my claim. I will defiantly shop for Bison products next time I need or want something in that line. Phil from Missouri

Block Party Success!~ We had a block party and needed plenty of ice. The afternoon before the event we filled our Bison 25 Quart cooler to the brim with bags of ice. and locked it down. The next afternoon there was barely any melting, still all cubes. The party was Friday evening. It's Monday late and I'm still tossing my beers in there to get them frosty for tomorrow! Still ice in the cooler after repeatedly being opened in warm temperatures. It's a wonderful product and we are very Impressed. Cheers!!
