S'well is the sleek, chic, stainless steel hot/cold thermos bottle that will replace your office coffee mug and Nalgene in one go. It keeps cold liquids cold for 24 hours and hot liquids hot for 12. Its body fits comfortably in your hand as well as in most cup holders and the opening is big enough for most ice cubes, but small enough for drip-free (and slurp-free) sips. Because this is one of S'well's premium bottle, it comes in a lightweight and flexible carrying bag to keep the luster finish in perfect condition. This multi-use bag is great for your polishing needs from jewelry to sunglasses, for smudge-free perfection.
