Butelka Summit z ustnikiem ze słomką

I’ve been using this bottle daily for a week now, and the vacuum insulation actually keeps my water ice-cold even after a full afternoon in the sun. The straw lid is easy to sip from without any leaks, which was my main concern.

Left it in the car during a 90-degree afternoon and the water was still icy cold hours later, which honestly shocked me. The straw lid clicks shut tight enough that I tossed it in my bag without a second thought. This is my new everyday bottle for sure.

Had a long outdoor shift and came back to find my water still ice-cold, which the double-wall insulation definitely delivers on. Only gripe is the straw lid takes a couple tries to click shut securely, but once it's closed, no leaks in my bag.
