EcoVessel Boss Vacuum Insulated Beer Growler, Large 64oz Stainless-Steel Water Jug with Removable Infuser and Triple Layer Insulation

I have a CraZy high standard for water bottles. If thermal performance isn't as good or better than my copper-layered Swell bottle, I don't even care to look at it. With that said, I kept running into the issue of running out of water when I wasn't around a tap. The 17oz Swell is just too small and the larger 24oz they offer is too cumbersome for my day to day carry -- enter Ecovessel, more specifically, the Boss Growler.While looking at copper-lined alternatives to Swell, I came across Colorado-based Ecovessel. They had similar thermal performance and looked to feature a much nicer cap design over the Swells and Hydro flasks I was used to. I ordered a couple of their 20oz Boulder Bottles for me and my wife which we liked a lot but still thought were too small, and agreed that anything larger would be too annoying to carry. Our solution? Get a giant one to put in the car to refill the 20oz Boulders when we get back to the car from hikes or whatnot. Swell charges a whopping $75 for their 64oz bottle, so Ecovessel's Boss was our ticket! At the time of purchase, Amazon had a 30% off coupon, which made this buy a total no-brainer. Now that we have it, I can verify that it made out of super high quality, durable materials. I look forward to taking this on adventures for years to come.About the cap design:This is a wide mouth bottle with a wide mouth cap that ALSO features a narrow mouth opening option. I find the cap to be the #1 thermal performance killer on other bottles, but this one is well thought out and doesn't seem to impact the temp as much as competitors. Great job, Ecovessel.This is likely the best 64oz bottle on the market. I recommend it in full, and highly suggest checking out Ecovessel's other product offerings. They all have the same copper layer and cap design (unless you opt for the staw variant.)

It keeps things hot and cold as advertised. I live where it gets 110 to 115 yet today it is 29 and my beverage is still hot. I've seen people complain that it does not keep ice for 150 hours but I'll tell you what when it's 115 it will still be cold 150 hours down the line. It works just as well as my yeti I have different sizes and different brands of the two.

Well made, eco-friendly, keeps things cool longer than any other water bottle on the market and by a large margin (to my knowledge--and I did a lot of research before purchasing). Bought my first water bottle from this company several years ago, which is still going strong. Highly recommend not just this bottle, but products from this company in general.

Received this item and really love ecovessel but this one smelled straight up like chemicals couldn’t drink out of it even bought the cleaning tablets didn’t even touch the smell ended up sending back for a refund really disappointed in this particular product

This is the best thing ever. The ultimate growler. Good for when your drinking with ice. Doesn't pass through the tea infuser. Drop it several times and still works. Even left it with a carbonated drink for a few days and didn't leak.
