DISSECTING THE
DARK KNIGHT.
Every weld, gasket, and surface treatment on the POWCAN 26 oz Insulated Water Bottle is engineered for maximum thermal stability and leak-proof performance. Here is our detailed construction teardown.
Savor Slow, Chug Fast
The versatile 2-in-1 lid simplifies beverage access. Flip up the straw to sip easily while working out or driving, or use the wide-mouthed spout for pouring and fast chugging when you need maximum hydration. The leak-proof gasket system ensures not a drop spills even when shaken upside down.


Double-Wall Vacuum Insulation
POWCAN features double-wall vacuum insulation to lock in temperature. By removing air molecules between the inner and outer 18/8 stainless steel walls, it eliminates conduction and convection. Keep your drinks ice-cold for 24 hours or cozy warm for 12 hours, with zero exterior condensation.
