Question: Does the black plastic loop cap leak like the others lids do?
Document: I have just purchased my second one of these since I use one all day long sipping on water. I like the stainless steel and the fact that there is no straw to get dirty or fall off. I feel like it is easier to clean than the stawed ones or plastic. PLUS it is NOT plastic... good, bad or unknown. I like the top with the molded ring. One can easily attach a clip to it for hooking to a pack or belt.
Excellent product. I would say that the sports cap is not leak proof. This is attributed to the small hole at the top to allow the free air flow when sipping from the mouth piece. Overall, it is excellent.
Love this bottle, only two complaints: 1) although the online description says dishwasher safe, the care instructions that come with suggest that the colored bottles should not be washed in the dishwasher. 2) the flow cap is good, but mine makes a squirrel-like whistling noise when you drink! I've found that if I press down on the air valve it is a little quieter, but this is slightly inconvenient. Not a deal breaker for me, but might be a problem for people wanting to sip discreetly.
Water really does taste better out of HEALTHY metal containers than plastic. They will sweat if you put ice in them, but you can purchase a case/holder than minimizes this. I will buy Klean Kanteen from now on.
I've had my Klean Kanteen for almost four years now. I bought this one for my girlfriend and she wanted the sport top so that she wouldn't have to remove the top every time that she needed to take a drink. What I've noticed from drinking out of it: You get a lot of air and the d-mn thing tweets like a bird when the air passes through the valve. Cool, but she's a teacher and it gets a laugh out of the kids every time she uses it.
Great bottle for water. Water tastes great out of this. I would suggest not buying one of the colored bottles. The paint on mine started chipping on first use and with little abuse. If I were to order another I would go with the stainless exterior. The sport top will also leak if the bottle is laid on its side.
Get stainless cap or the Cap 3.0 might be better.
Unfortunately, the manufacturer sells a good product and then adds the "Poly Sport Cap" which leaks under most circumstances and gurgles and whistles whenever one drinks! The cap is so faulty that it damages the overall reputation and experience of using a generally well-designed bottle. Would never recommend the sport cap.
This cap 2.0 pours water out when upside down. It does not hold water at all due to the air bypass design to allow quick drinking/air replacement. The packaging on arrival notes this. I did not see that disclaimer on Amazon. Cap 2.0 is a rip off and is good for only uses cases when the bottle is always upright.Bottle quality is good, get different cap or competing provider.
I cannot believe how fast this came and am a huge fan of klean kanteen for my whole family! The size is perfect for adults.
