I've been using the Camelbak Long Neck 3L bladder for the past 15 years......it's great, and very easy to refill it with a filter through the drink tube.
Platypus. I use a 2L hoser for short training hikes and a 3L big zip for hunts. I have had the hoser for over 12 years with zero issues. I like the quick disconnect on my big zip because my filter plugs right in without pulling it from my pack.
Source Hydration. Imparts no taste, and has a neat accessory that let's you fill the bladder without removing it from your bag. I've been pretty rough on mine without experiencing leaks.
For those still coming to the thread, my addition would be: MSR Dromedary (especially the old kind with a light Cordura-style outer) for bulk storage/camp cartage, and Source for a hydration/hose-connected drinking bladder. Both have been leakproof and even drop-proof for me ... and work really well together as a system.
I run a collapsible 1 liter bottle then pair it with a 10 liter MSR Dromedary bag. It is a slick set up as my bag stays dry, I can have a lot of water if needed, or less if I dont want to carry the weight.

Those Dromedary bags are also excellent warm weather pillows. I wouldn't suggest it in freezing temps, but I've never found a more comfortable place to lay my head after being out in the swamp, etc.
Osprey Hydraulics - quick detach hose is easy to mange and insert inline filter, and the whole top opening (vs a bottle style screw cap) makes is much easier to fill and clean.
I'm also in the market for a new bladder. I have a gift card for REI so really wanting to keep the purchase there. I would've bought a 3L Platypus but REI doesn't carry it, only the 2l.
Also, there's a lot of bad reviews of the Platypus with the full open top. I know older Platypus bladders were great, but sounds like the newer Big Zip is a downgrade.
I like the idea of an fully open top for better cleaning and drying. What recommendations does people have specifically for 3L with a fully open top option?
Anyone use the CampX 3L water bladder? on Amazon for 19.99... I just got it because sometimes the cheap stuff works great! will put it to the test on my next scouting trip.
