Customer Reviews
Detailed Flask Review
I ordered the 40oz Wide Mouth Flask along with a Straw Lid Attachment and a Boot Sleeve Protector. The ordering process was straightforward on their website; I found what I needed easily. Shipping took about a week, which was within the estimated timeframe. The flask arrived well-packaged and felt substantial. The Boot Sleeve Protector fit snugly and feels like it will prevent dings. The Straw Lid Attachment works well, making it easier to drink without unscrewing the whole cap. I tested it by filling it with ice and water, and after 12 hours, there was still a good amount of ice left. Cleaning the straw lid took a little effort, but the Cleaning Brush Kit (which I got separately) helped a lot. Overall, it's a quality product that performs as advertised.
Keeps drinks cold
Bought the 32oz Insulated Water Bottle. It keeps water cold all day. No leaks. Good product.
Worth the money
I was looking for a good deal on an insulated bottle and found Frost Flask. I bought the 32oz Insulated Water Bottle during their holiday sale, which gave me 20% off. The bottle itself feels really sturdy, and my ice water stayed cold for most of a 10-hour day. I usually compare prices a lot, and this was definitely a solid buy for the quality. Free shipping on top of the discount made it a smart choice.
Love my new tumbler!
I just received my new Stainless Steel Tumbler and I absolutely love it! My iced tea stayed perfectly cold all afternoon while I was working outside. The color is even better in person. I'm so glad I got it. I'm already planning to get another one for my friend's birthday next month. Definitely recommend Frost Flask to everyone!
Reliable as always
This was my third purchase from Frost Flask. I needed a new Coffee Mug with Lid, and this one didn't disappoint. My first one, a 40oz Wide Mouth Flask, is still going strong after a year. This new mug holds my coffee hot for hours, just like my old one did. The quality is consistent, which is why I keep coming back. Shipping was quick this time, faster than my last order actually, which was a pleasant surprise.

I'm a student, do they offer any kind of discount for us? Trying to save a few bucks.
Are their bottles actually legit stainless steel or is it some cheap knock-off stuff? Don't want something that's gonna rust.
Hey, thinking about grabbing a couple of bottles from Frost Flask. Does anyone know if they do free shipping or what the deal is there?
Just wondering about the return policy. In case the color isn't quite right or something, is it a hassle to send stuff back?
Can I use two coupon codes at once? Got a first-order discount but also saw a deal on a bundle.
Hey guys, thinking of getting the 40oz Wide Mouth Flask. Does anyone know how long these actually take to arrive in, say, California?
How do these compare to Hydro Flasks? Are they pretty much the same quality?
