Just picked up this bad boy yesterday from Big 5's One-Day Sale for $18. They normally go for $29, so I'd say this is a steal.I normally use ice to keep my liquids cold, but with the insulation, if I put in my liquids already cold, I dont need ice, which means I can put in more liquids without the ice, yet the liquids stay cold.Not only is the 40 ounce container the perfect size, but, the durability of this thermos prevents it from getting damaged easily.

Awesome Water Bottle

I was looking for a water bottle that could keep my water and other cold beverages cold throughout the day, and I was fortunate enough to find the Fifty/Fifty Double Walled Water Bottle. This item is everything as advertised and I would highly recommend it to anyone. There are also other tops that you can use for coffee/tea sipping as well as a top that has a straw for those who don't like the wide mouth. Me personally, I love the wide mouth. Great buy great price built to last a lifetime. Just make sure you find a Sharpe edge or thin object so you can pull out the rubber seal to wash it by hand delicately. Those have a tendency to obtain bacteria so I recommend washing it 2-3/week. I'm a germaphobe though ;-)

Every day use.

I bought this bottle for work a few weeks ago and found myself using it every day. Water stays cold and I don’t add ice to it at all. I haven’t used it for warm drinks but I can feel it get really warm when I wash it. The handle is one of the main reasons I bought this as I am usually out of the office walking around talking to customers. It is has very good ergonomics.The size was also a selling point as if it’s a 2 litre it gets too heavy when walking around. The smaller size bottles I find myself refilling too many times.Plenty of positives with this bottle. I love the colour too. My only concern is I hope the colour stays on and doesn’t chip off over time.

Good Value Stainless Steel

I wanted a bottle that was stainless steel and insulated. This bottle is big enough for cold water that would last the second half of a long day hike. When winter comes around it will be good for hot drinks too. We have filled these with hot curry before when we wanted to save on healthy lunches at the ski resort too. Really good idea for opposite to ambient temperature food and drink.

LOVE THIS

I now have one of these drink bottles in every size. I first got the smaller one and loved it so much that i got the 750ml one, i just recently upgraded to the 1.1L and im using the lid with the straw from my smaller size bottle. Honestly, these drink bottles keep things cold for ages. I had mine in my room and came back almost 24hrs later and it was still cold! not room temp like other bottles. I highly recommend.

Poor design. Sipping lid sold separately. $$$

Come on............you can't even drink out of this without being perfectly still. No drinking while walking, on a stationary bike, driving etc.It's stupid that you have to buy a separate cap with a sipper lid, and that sipper lid has no handle on it, so you have to hold onto the bottle the whole time.I don't design water bottles for a living, but I could have done a dam sight better than you guys. (sorry, they won't let me swear)

Quality product, good value

Used daily in harsh, fifo mining environment. Used the previous one for more than two years.Old one still works, just well worn. Value for money.

Too big for the cup holders

Fifty Fifty water bottles are great, and keep water cool even in a hot car. Unfortunately had to return this one as it didn't fit into the cup holders of the car. Looks like it should have, but just too big :(

Very Disappointing

I bought this water bottle last week and it is very disappointing.It definitely doesn't keep liquids cold all day as advertised. I used it as my office water bottle last week and it only kept itself cold till maybe lunch time. Definitely not worth its price point of $60

keeps ice for a long time.

Works well and keeps ice for a good 6+ hours. Only two issues I can think of. The inside cylinder has a seam on the bottom edge that might be a bugger to get/keep clean. Second issue is the lid has a few sharp edges from the moulding process.
