"Straw Lid Versus Spout Lid: So Which Bottle Wins? Keep Cold Tested... Dark Knight (Sports)" We’ve been testing the 26 oz Dark Knight insulated water bottle to see how it stacks up between its 2-in-1 straw and spout lids. First impressions? The straw lid is perfect for sipping on the go, keeping our hands clean, but the spout offers faster drinking for intense workouts. When it comes to keeping cold, both lids held ice for 24 hours, though we noticed the spout might retain temp slightly longer. The Dark Knight design, with its sleek stainless steel and leak-proof seal, is a hit for sports and travel. The cup holder fit was snug, and the straw’s flexible tip glides smoothly. Our verdict? Both lids excel, but the spout wins for efficiency, while the straw edges out for hygiene. Either way, this bottle is a winner in our books."
