I purchased the Ultimate Direction Grind 12 Hydration Pack - Mirage Grey here when it was last offered. I have not had a chance to use it yet, but I am very impressed with the quality and features. Looking forward to using it soon.
I bought the Ultimate Direction Katoa pack one of the previous times it was one here for long bike trips and it works very well. The only advice I would have is that if you’ve never used the kicker top bottles before they take a second to figure out as you have to pull the kicker up before you can drink from it.
