Rated 5 out of 5 by from Fine tool for the job. This is a very durable bottle for room temperature liquid applications. If you want the water cold go thermal. The sport cap leaks a bit but not a problem if kept upright in your pack. The loop lid is bullet proof and ideal for day pack, golf bag, or any application where the bottle gets thrown around or left on its side for extended periods. Very lightweight when empty. Easy to clean. The carburetor on the sport cap is rather noisy when dispensing unless you use a finger to muffle. Sounds like your sucking that last bit of shake from the bottom of a paper cup. Still a 5 star product when both caps are available for specific duty.

Rated 4 out of 5 by from Great purchase Love this bottle, the only things I don't like about it are mostly my fault. I ordered this bottle for coffee not realizing that it wasn't insulated, and it gets VERY hot (or very cold depending on what is inside) and it hurt to touch (the instructions that came with the bottle said don't put hot liquids in, so it's not like they don't warn you, but I didn't see this on the website,) however this was an easy fix with ordering a $2 bonison water bottle sleeve on Amazon. The bottle also sweats a lot with cold water, but the sleeve helped that too. Other than those two aspects, no complaints with the bottle. Really really great purchase, and very fast shipping.

Rated 5 out of 5 by from Amazing!! You should totally buy one! The Klean Kanteen company sent my class 30 classic 18 ounce water bottles! In our computer class my teacher told us to write a letter requesting products. I choose this company because I love all of there products. The next week they sent me and my classmates water bottles. I wrote them back with a thank you letter and now I am writing a review. We tried them all out and everybody loved them! They loved the mouth and how it was sealed very nicely. We only have 1 little recommendation, the water bottle gets really cold when you touch, Yes I get it you can get insulated ones, but if you put ice water in them, they get very cold. Otherwise they are perfectly fine and I totally recommend them for everybody.

Rated 1 out of 5 by from Disappointed with leaking and unsanitary top I am forever in search of water bottles that will fit in my teenagers' lunchboxes that don't leak. I was hopeful for these 18oz. Klean Kanteens with the sport caps, but was very disappointed. The kids complained about the water bottle leaking all over the lunchbox and also about the wanting a cover for the spout (because the inside of the lunchbox is not always so clean...). These water bottles failed on both of those fronts and unfortunately I had bought 4 for $80. Complete waste of money.

Rated 4 out of 5 by from Branding Klean Kanteens are well known for their exceptional durability and usefulness. The Classic 18oz is the perfect size for quick liquid hauls, whatever they may be. I don't have to worry about spills and all the scratches acquired over time only enhances the appearance of the Klean Kanteen; which is why I think the logo could be printed smaller on the bottles. At this point, the product speaks for itself. No need to blast the branding. A more subtle approach to printing the Klean Kanteen logo on the exterior is a tasteful and radical way to approach product awareness.

Rated 4 out of 5 by from Overall bottle is ok Overall bottle is ok, but still has a problem with a sport cap, the air valve construction is still not reliable. I bought two bottles and one is ok, the other one had a problem with leaking. The problem is that valve fails to close after you stop drinking and close the main drinking valve, you could notice the by the visible part of the air valve on the upper part of the cap. One of the solution os to blow in the drinking valve before you close it, this may help to close the air valve by the air pressure you develop in the bottle)

Rated 5 out of 5 by from Great water bottles Seems silly to post a review on only one color, but here goes. We've used klean kanteen water bottles for years. Durable and leak-proof (with the right lid, properly tightened). The sport tops are leak resistant but not leak proof. One of my favorite aspects of klean kanteen water bottles is the lids. They're all interchangable and replacable. So we never end up with the problem of lids without bottles and bottles without lids. Grab any size bottle and any lid and they'll fit together. Makes our lives much simpler.

Rated 4 out of 5 by from Love it but the lid leaks I bought these for both my kids. (ages 3 and 5 at the time) and LOVE them! They have been dragged, dropped, kicked and put through much abuse. Occasionally we have to take a hammer to the bottom to get the dents out, but 4 years later they are still going strong. My only issue with them is the lids will tend to dribble. My young kids didn't have the coordination or strength to work the twist tops but the sport tops will dribble when left laying down or being tossed about in a backpack.
