Best hydration pack i've ever used! - Geigerrig Hydration Pack Engine Reservoir

This thing is great! It's only been on one 3-day trip so far, but it feels incredibly durable, even when it's pressurized. The pressurization system sometimes needs a little help sometimes to maintain pressure, but it works well enough that this was the only water container I used all weekend. The open-top system makes it easy to fill and clean, and the in-line filter I picked up clips right in and means you can fill and drink on the trail without ever slowing down. 3 liters was probably a little large for hiking on the east coast, but I'd rather carry more water and stop less. It's a fantastic bladder that's worth every penny.
