HASLE OUTFITTERS packs twelve 20oz stainless steel tumblers into a single box, making this a bulk buy that actually makes sense. The mint green color and classic silhouette lean into a holiday theme without being gimmicky. Each tumbler uses a double wall vacuum insulated construction, which keeps coffee hot for hours and iced drinks cold without sweating on your table.

The 304 stainless steel liner is thickened and welded properly. No metallic taste, no rust spots after a few dishwasher cycles. The handle is welded on, not glued or clipped, so it holds up when you’re carrying a full mug across the office or campsite. The lid is the real standout here. It slides to seal completely for leak-proof transport, then opens to a drinking hole that allows for easy sipping without spilling. You get two ways to drink: closed for travel, open for desk use.

At 20oz, these are a solid middle ground. Large enough for a proper coffee or tea, small enough to fit under most brewers. The finish is smooth and the mint green color holds up well against scratches. If you need a dozen matching tumblers for a gathering, an office, or a holiday event, this set delivers consistent performance without fuss.
