The CamelBak® Forge Flow 16oz has a leakproof cap and self-sealing, one-handed drink lever that work together with the vacuum-insulated stainless steel to keep drink temps right where you like them for hours – without spilling a drop. The convenient free-flow lock button slides open for easy sipping and cooling. Durable enough for your daily grind, the exterior is dressed in a full powder-coat finish and sits steadily upon a non-slip silicone base.
