Second time purchasing these bottles-they're the best: light weight, insulated, keep your drinks cold, fit nice and snug in standard bike cage. Can put into the dishwasher, but will lose insulating ability over time-best to hand wash as recommended. Caps can get grody with use of chapstick-may require a dishwasher run. Bottle sometimes makes clicking noises when valve is open-requires squeeze to release.
Agree with the reviewers about liking the cap-whole bottle is easy to keep clean and cap makes easy to carry. Bottle also fits in a standard cage for biking around town. Dropped my last one and yes, it dented, but not so bad it would not stand up-did crack the inner lining though-definite drawback to using these types of bottles. Importantly these bottles have no associated metallic taste-water tastes like...nothing-as it should! Keeps cold better than a plastic types, not too heavy.
