زجاجة ماء Summit بغطاء شفاط

It’s been sitting in my car through a 90-degree afternoon and the water’s still ice-cold hours later — that double-walled insulation really pulls its weight. The straw lid clicks shut and I’ve tossed it in my bag without a single leak.

Bought this for hikes and it keeps water ice-cold for a solid few hours even in direct sun. The vacuum insulation works well, and the straw lid pops open easily with one thumb.

The straw lid seals tightly even when I tossed it sideways in my bag, which is a relief. My water stayed noticeably cold for a good six hours on a warm afternoon. Just wish the mouthpiece was a tad wider for easier cleaning.
