Geigerrig hydration engine reservoir - thank you - Geigerrig Hydration Pack Engine Reservoir

After reviewing several hydration pack articles, I bought two Geigerrig engines (one for me, one for my partner) and we field-tested them on the one-day Tongariro alpine crossing in New Zealand. They performed admirably, with a good capacity, a well-designed bite valve, and easy (pressurized) flow. The ability to turn the bladder inside out for dishwasher cleaning is great. Very pleased with these purchases, and will be using them more in the future.
