Since the Hydrapak Force2 Reservoir combo has been discontinued the company has continued to offer a similar “pump” drink tube compatible with their other reservoirs including their 2L Shapeshift also sold here.
The pump can be set up as it’s shown, or using the soft plastic drink nozzle that comes standard on the Force2 Reservoir which is simpler for humans and durable for dogs.
If you’ve had issues with getting enough water out of your reservoir quickly, this system should help. We’ve used them and they really move water!
The pump is also adaptable to most other reservoirs, all those with 3/8″ hoses like Camelback and others.
