Stanley makes great, iconic, blue-collar products. The green thermos is a staple in the American workforce, and their brand is known to be rugged and timeless.
The same is true with a newer product they're launching: the Happy Hour Shaker with Four Cups. This nifty gadget gives you everything you need to make cocktails while on the go. Camping, hiking... even at work. (Just in theory, of course!)
The shaker is a nested system that stacks the four cups inside of the shaker, along with a juice reamer. The kit is made with 18/8 stainless steel, which is naturally BPA free and dishwasher safe. The glasses are double-walled rock glasses that cool your drink and keep them sweat free. Oh, and Stanley products have a lifetime guarantee.
You can also buy a two-glass set, if you're more of an introvert.
