Two lids ship with this 22 oz bottle: a wide mouth cap for filling and quick drinking, and a flip-up straw lid that opens at 95 degrees for sipping mid-workout. The 2.16 inch opening takes ice cubes and a bottle brush without a fight. Insulation comes from four layers, a painted coating over 304 stainless steel, a vacuum gap, then a second 304 stainless wall, which holds drinks hot for 12 hours or cold for 24. A 360-degree sealing ring keeps it leak-proof and spill-proof inside a bag. At 0.9 lbs empty and 3 inches across by 9.6 inches tall, it slides into most cup holders and pack side pockets, and the easy-grip handle carries it while camping, hiking or cycling.
