Don't go out in the cold without it

  • Familiarity:I've put it through the wringer

I was never much of a hot drink on the trail kind of guy. I would have a coffee on my way somewhere, but now, I can't leave home without this. Dawn patrol, hot coffee. Late night excursion, hot toddies. Trust me, you won't be disappointed. It does fit into a large cup holder. Its surprisingly light weight compared to a traditional thermos. It's very easy to clean, even if you accidentally leave something in it for a while. It probably won't fit into a pack sleeve, so I keep it in the top of my pack, tilted sideways, and have all the confidence that it will not leak.

Durable, As Advertised, and nice looking

  • Familiarity:I've put it through the wringer

I personally use several 25 oz size of the Boulder water bottles on a daily basis. It's great during my busy day to be able to pick up the bottle off my desk and take sips and they are always cold.

I also take it hiking, put it in my backpack, and have put carbonated beverages in it without a problem or leaks. During daily use it get bumped around and dropped occasionally and I have found it to very durable in those regards.

Keeps things cold in the summer even in a hot car for many hours as advertised. I have not really tested it with hot beverages as I don't tend to drink them.

Best Bottles for Your Favorite Tea

  • Familiarity:I've put it through the wringer

Fantastic Bottle, bought it in all 3 sizes, 17 oz, 25 oz, and 45 oz. 17 for keeping a fresh drink handy around the house and yard, 25 for short excursions, and I especially like the 45 because I can cold or hot brew tea that is available to me all day. The strainer makes it particularly nice for cold brewing my favorite herb teas, with lots of flavor and no bitterness.

The best bottle ever!!!

  • Familiarity:I've put it through the wringer

I love these bottles so much that I bought one for every member of my family and now get them as gifts!! It will keep your water cold even out on a hot beach all day!! Try it you won't be disappointed!!

Love this bottle!

  • Familiarity:I've put it through the wringer

This has good capacity, keeps water cold (ice stays for over 18 hours) and does not leak. Also, there is no plastic anywhere on the exterior, so withstands drops without cracking!

Rugged, easy to clean, nothing compares

  • Familiarity:I've put it through the wringer

I bought this bottle for my husband this past summer and it has proven itself over and over again. Exactly as advertised, keeps cold things cold and hot stuff hot. It's also very easy to clean out and looks stylish. I love the option of two spouts and the attached lid. Nothing compares to our Eco Vessel bottles! We used to have a collection of Camelbak bottles but ditched the plastic for stainless steel and never looking back.

The Boulder Takes Abuse and Remains 100%

  • Familiarity:I've put it through the wringer

I wanted to let you know how much I love my Eco Vessel.

I prefer COLD drinks and it does the trick. Nothing else I have tried holds a candle to my Eco Vessel "Boulder" - 25 oz.

Recently, while camping in Yellowstone National Park and dropped in while hiking on the path to Tower Falls. It banged down the trail, but lucky for me it stopped when it hit a large rock. It won't sit level anymore, but I still carry it with me almost constantly.

Best water bottle ever!

  • Familiarity:I've put it through the wringer

No funny taste. No sweating, keeps water cold for a very long time...even in a hot vehicle! I bought one in a little Door County store and loved it so much I ordered another on-line. You need one! They are amazing! I will be ordering another for my 3 year old.

Love this product

  • Familiarity:I've put it through the wringer

I love that this keeps water cold all day long, even in a hot car. Very easy to clean. I have 2 25 oz and 2 17 oz bottles that I use constantly. My kids have a bunch of the smaller ones and we use them everyday for school and sports.

This is a great product.

  • Familiarity:I've put it through the wringer

I love this. I was really sold when I had filled it with ice and water then forgot it in my car for the day when I went to work. And yes it does fit just fine in the cup holder. After sitting in my closed car on a day where the outside temperature reached 103 and inside the car it was at least 125 I was shocked to find almost as much ice left as there was in the morning. Highly recommend.

This is the "Magic bottle"

  • Familiarity:I've put it through the wringer

This is the best bottle I have owned. My daughters play soccer and they have used this bottle for the last couple of years and it has held up well. Her teammates call it "the canteen" and are requesting their own because she is the only one who has ice cold water throughout the games. I have used this bottle and it still has ice in it the next day. I love the fact that it has a larger opening which is easier to put ice in and a smaller opening to drink from. This product is great. My girls call it the "magic bottle." I have two of them. You won't regret this purchase!

Keeps your cold drinks cold...

  • Familiarity:I gave it as a gift but have feedback to share

I gave two of these bottles as gifts and they work perfectly. They are durable, lightweight, and keep your cold beverages actually cold and the hot ones hot. I have not had the opportunity to try cleaning this bottle, but I suspect that it would be fairly easy with a scrubber. One feature that is rare on a bottle, but really nice is the removable strainer. This would be perfect if you are a big tea drinker or if you do not wish to have a mouth full of ice when trying to drink out of a bottle. Each of the bottles I purchased was black and they kept the water inside cold even when sitting in direct sunshine for hours. One downside is that the material will scuff if dropped, but I would say all around these bottle are very durable and a great buy.

Finally got mine back.

  • Familiarity:I've put it through the wringer

I had to buy three of these. One for my wife and one for each of my kids because they kept stealing my water because it was the only water bottle in the family that would still be cold after a long hike, etc. I can literally leave this bottle filled with ice water in my car in 100+ degree weather all day and come back to frosty cold water.

Best insulated bottle I have purchased

  • Familiarity:I've used it several times

This item really does hold up to its claims. I have had other brands of insulated bottles, but most of them have leaky drinking tops, and they do not retain the cold as well as the Eco Vessel. Another plus, the cap is like a regular water bottle so one can drink without the inevitable, annoying slurping sound of most drinking tops. One word of advice: chill your liquids first before you put them in the container. It is so well insulated that popping it into a fridge does not affect the liquid inside.
