Nice bladder, long hoser
Never thought I'd say, "hey, nice bladder" to a Platypus, but this a nice, basic bladder that can be used with most hydration compatible backpacks. I use a 3L with my Arrakis 50 and keep another 2L filled for longer trips or for when it's hot out and I think I'll need the water. No weird tastes, aired out after every use.
The hoser is a little long, requiring me to creatively route the tubing carefully as to avoid kinking.
