Butelka Summit ze słomką

The straw lid is genuinely leak-proof — I tossed it in my work bag sideways with coffee and not a drop escaped. Even after a full afternoon in a hot car, the water stayed cold enough to be refreshing, which is exactly what I needed for summer hikes.

The double-wall insulation actually keeps my water ice-cold for a full workday, which is exactly what I needed. The straw lid seals tight enough that I can toss it in my bag without worrying about leaks. Only small gripe is the straw itself feels a bit flimsy.

With the nozzle closed I’ve tossed it sideways in my bag and not a drop escaped, really convenient. The double-wall insulation keeps water cold through a long afternoon hike. Only wish the straw was a tiny bit stiffer for easier sipping.
