The SOURCE Tactical WXP 3L bladder is my (Brian’s) absolute second favorite bladder. With that in mind it’s pretty much everyone else’s favorite bladder. It’s time tested and one of the most popular bladders you will see at a GORUCK event.
When it comes to GORUCK events I’ve had weird luck with bladders. The first I bought was a CamelBak and it broke on me during my first event. The second I bought was an MSR Dromedary 4L which has a tendency to leak everywhere. The third bladder I bought was from Source and (back in 2012) and it’s still working to this day. I’ve replaced the hose on it once but that was it.
Between 2012 and present I’ve bought a number of Source bladders to keep around for guests but I’ve never had to replace one. I consider myself pretty lucky in this regard but, because of that, Source is the bladder I recommend for GORUCK events.
If this is your first bladder purchase and your backpack has webbing then don’t forget to pick up an ITW GrimLoc. You won’t regret using one keep your hydration hose in check.
