12oz. Chill 保冷套（適用於 12oz. 塑膠瓶）

The matte texture really helps me grip my bottle, and it fits snugly without sliding around. I grabbed a couple colors to swap out during the week, and they’ve kept my water noticeably colder on hot walks.

I was worried about condensation dripping everywhere during my hike, but this sleeve completely solved that—the inside lining keeps my bottle bone-dry while the outside fabric has a nice, non-slip grip. Snug fit on the 12oz bottle, too.

The textured fabric on the outside actually gives enough grip that I’m not fumbling for my bottle during my morning walk. It slipped right onto my bottle and has kept my water cold for hours—way better than the bare plastic.
