보온병 엘립스 900ml - 노르딕 블랙

Left a bottle of sparkling water in my bag all day and it was still fizzing when I cracked it open that evening—the carbonation-safe lid really works. The 900 ml size fits my car cup holder, which is rare. Cold stays cold for a full day, easy.

Took it on a three-day hike and the water was still icy on the second morning, which is exactly the 24-hour cold promise. The lid seals tight enough that I finally stopped worrying about leaks in my bag.

Took this on a long train ride and the coffee was still steaming at hour eleven, which honestly shocked me. The 900 ml size fits perfectly in my bag's side pocket, and it handled sparkling water without any fizz explosion when I opened it later.
