After dropping it on its backside in addition to on its lid, the bottle barely confirmed indicators of abuse, apart from some paint chipping on the underside.

Coming in at 21 ounces, its success throughout the drop take a look at could have been as a consequence of it being one of many lighter choices, although the 26-ounce Yeti and different smaller bottles we examined didn’t carry out as nicely when given the identical remedy.

The place the Stein falls a tad quick is its lid and mouth. The mouth isn’t practically as huge because the Rambler’s, so whereas filling up the bottle isn’t a chore, it’s positively tougher to get ice in as rapidly as you may with the Yeti. The lid comes geared up with a carabiner and didn’t retain any bitterness after our espresso take a look at; nonetheless, it’s a easy screw-on lid, so that you drink instantly from the bottle’s mouth as a substitute of from a spout.

The Miir additionally did nicely in thermoregulation, outdoing each the Yeti and Sigg. Nonetheless, it misplaced favor throughout the drop take a look at, when the lid broke on the primary drop.
