We have good news — Amazon is featuring a pretty awesome Prime Day deal on Stanley's popular 2-quart vacuum-insulated bottle for just $33 (was $51). If the past has taught us anything, it's that these babies are gonna fly off the shelves ... fair warning.

This 64-ounce behemoth is sure to keep you hydrated for hours on end — and you won't be sipping on lukewarm liquid, either. The container's double-wall vacuum insulation ensures your drink stays hot or cold for up to 24 hours. Plus, it's made from durable, BPA-free stainless steel, so it's going to last you for years. It's travel-friendly, thermo-regulating and dishwasher-safe.

In addition to all of the aforementioned bells and whistles, the Stanley Classic Vacuum Insulated Bottle has a leak-resistant screw-on lid, plus a cup that holds 8 ounces of liquid. Another convenient feature is the collapsible handle, which makes for easy transport — a good thing, because you'll want to bring this jug with you to the beach, picnics, après ski at the mountain and beyond.

"Love this thermos. It’s huge. Enough tea or coffee for a whole workday. Attached drinking cup is a little small but I use it to fill my full-sized cup," wrote one happy customer.

"I have the smaller 1.1 qt. Stanley thermos that I use daily at work and when going on road trips," said another impressed customer, adding, "I wanted a larger Stanley thermos and have been looking at this one for a while. The black matte finish is flawless and will make it easier to identify from [my] smaller green thermos."

"This is a solid, heavy thermos that holds a lot of liquid. If you fill it to the top, it will fill the cup 11 times. It also keeps your tea, coffee, whatever, very hot," raved a satisfied reviewer.

Whether you're enjoying hot drinks after a day on the slopes or cool ones during a summer picnic, the Stanley Classic Vacuum Insulated Bottle will quickly become one of your favorite investments.

It's made from durable, BPA-free stainless steel that's dishwasher-safe.
