Cold Pint
$23; BASSPRO.COMStanley has been making thermal con-
tainers for the lunch-bucket crowd since
1913, and it’s hard to imagine how the Yeti
crowd trampled them — unless it’s the
cache of refilling your Stanley versus your
Yeti. Regardless, the Cold Pint fits the
hand well and slips easily into cup holders
in the car and boat. It has a larger sipping
hole, which accommodates safer slurping
of hot coffee, but it also accounts for the
ice melting faster.
EXTRA POINT: I’ll be darned if there isn’t
a stainless-steel bottle opener in the lid.

Adventure Packable Locking Mug
$20; WESTMARINE.COMWe had high hopes for this one, but they
were dashed early in the test as the cup
began to sweat. Never let them see you
sweat. It is a handy size and shape for
easy gripping or for slipping into cup hold-
ers. A stainless-steel D-ring fastens it to a
tackle bag or pack. In the mug’s defense,
it’s only advertised to hold its temp for
90 minutes.
EXTRA POINT: The lid closes and locks
with a slide, making it possible to throw
a full container in a bag without fear of
it leaking.

30-ounce Tumbler
$40; ENGELCOOLERS.COMThis is the magnum cold-cup size and
intended to keep you refreshed from
dawn at the ramp to afternoon at the
fish-cleaning table. Its lid is standard, and,
instead of pressing on, it screws on tightly,
closing the silicone gasket positively. I’ve
dropped mine a couple of times, and the
lid has remained in place. Engel doesn’t
specify what stainless steel it uses, but the
material has no ill effects after a month at
sea and leaves no metallic taste.
EXTRA POINT: The standard lid boasts a
closing tab that keeps your drink sealed
tight, even if it’s upside down.
