Best cup I’ve had to date and I have every brand.

I carry water to bed with me every night, and there is always ice still in it the next morning. The spill proof lid is also great. This one is a gift for a friend of mine. I would definitely recommend this item.

Great Tumbler, performs better than my Yeti tumbler, plus its made by a local company based in TX. The twist on lid is solid and doesn't leak. I have switched from buying Yeti to Bison products, and in my opinion, Bison is better quality. This means you get a premium brand and product without paying more for a marketing gimmick.

really like that the lid screws off as opposed to pop up. works great.
