"I'm a true Iron Flask fan—this 40 oz is part of my growing collection. Every one I've owned still performs perfectly, even after years of use and a few accidents. The three lids are so handy for different activities, and cleaning is a breeze. I recommend these to everyone I know."

"I work from home and wanted a bottle that fits my desk and car cup holder. This one keeps my drinks cold all day, never sweats, and never leaks on my papers.

"I've tried lots of different flasks, but these remain my favorite. The flow rate is simply better than anything else out there, and I like that the material is soft yet durable. The only thing is that they're not the easiest to clean if you don't use only water, so I make sure to rinse them out right after each use."

The compact straw design is discreet and convenient during meetings, and the bottle fits perfectly in my car's cup holder. It never sweats or leaks, even when I accidentally knock it over.

"I recently picked up the FITLY Soft Flask for hiking and running, and it’s quickly become essential to my routine. The flexible design means it shrinks as I drink, so there’s no sloshing, and it’s comfortable to carry. Build quality is impressive, and the wide mouth makes cleaning and filling simple. The cap and nozzle never leak, and it’s easy to sip one-handed while on the move. When empty, it folds down really small for easy storage. I highly recommend it for anyone needing a reliable hydration solution on the go."

"As someone who works in a tough factory environment, I needed something that could take a beating. This water bottle is an absolute workhorse—it’s survived drops on concrete and steel without a problem. The insulation is fantastic, keeping my water icy cold for hours. I also love the eye-catching iridescent color and that the wide mouth makes it easy to fill and drink from. Even after months of use, the exterior is barely scratched, just a little dented."

"These flasks were exactly what I needed—affordable, easy to hide, and completely leak-proof. The included funnels made filling them a breeze, and they held up even after being squished into tight spaces at events. Perfect for sneaking drinks into concerts or waterparks without worrying about metal detectors or spills. Will absolutely keep using these for future outings!"

"I brought a few of these on a camping trip and was impressed by how well they sealed and fit into my pack. They're ultralight and flexible, perfect for backpacking. While I think each flask is good for a couple of uses before replacing, they’re exactly what I needed for a lightweight setup."

"I've been using Iron Flask bottles for years, and they consistently keep my water ice cold all day long. Even after being dropped and scraped, the insulation and seal have never failed. I love that it comes with three lids, so I can switch depending on my activity. They're super easy to clean and look great. I keep recommending them to friends and have never had a complaint."

"My Iron Flask has survived road trips, camping, fishing, and daily work—it's tough as nails. I've even tried smashing it in frustration, but it's so sturdy it just won't quit. When it once fell into a lake, no water got inside thanks to the excellent seal. It actually outperforms my Yeti bottle. If I ever need a new one, I'm definitely buying another Iron Flask."

"I replaced my old bottle with this one and was pleasantly surprised by how much longer my water stays cold—even after flights and road trips. No leaks at all, and it's easy to clean. The color is lovely, and even after a few drops, it hasn't dented or scratched. I liked it so much I bought more for family!"
