Our popular 26.2 math miles design is laser engraved on this stainless steel hot and cold running travel tumbler that's an ideal gift for a marathon runner. The 20 oz. insulated tumbler is an all-season travel tumbler designed to extend the amount of time hot drinks will stay hot and cold drinks will stay cold, using double-wall vacuum insulation that works overtime to ensure drinks can be enjoyed at their optimal temperatures. The unique design helps minimize potential spills and can be used in moving vehicles or while on the go. Perfect for commuting to or from work, as well as to use while there, on day trips or when traveling, or as an everyday travel bottle, it is a great gift for a runner, post-race or for any occasion.
