Kubek The Quencher H2.0 Flowstate™ | 40 OZ

I take this thing to the gym and on my hour-long commute, and the lid’s twist-off seal feels solid even when I toss it in my bag. Ice from the morning is still clanking around by late afternoon, which honestly shocks me every time.

Took this on a long commute and the drink was still ice-cold three hours later, exactly as promised. The straw lid seals tight when flipped shut, so not a single drop spilled in my bag.

The straw lid seals tight enough that I can toss this in my gym bag without a single leak, and the 40 oz size means I’m not refilling mid-shift. It kept my iced coffee cold through a four-hour errand run, though the handle is a bit awkward to grip when it’s full. Solid buy for the price.
