What size/make hydration system are those with a recon harness using?
I'm looking to add the harness to my snubby kb for carrying more water when mountain biking.
I'm using a Source Hydration 3 liter. Most of the time I don't fill it up all the way....maybe 2/3 or 3/4 full. Seems to work pretty good for me and the models from The Source Hydration are about the only ones that I haven't had leakage problems from. Here's the model I am running in mine: https://sourcetacticalgear.com/tactic...torm-valve.html
I also have one of these, which allows me to fill the bladder from a tap or small opening bottle without having to remove it from the slot on my Recon Harness: https://sourcetacticalgear.com/hydrat...on-adapter.html
I also use a Source Tactical bladder as well; most of my outings are in water rich environs, so the 1 liter gets the call most often
I like the 1 liter as it gives me room for some shelter bits underneath the bladder
I am using a Platapus 3L Hoser bladder. I rarely fill it with more than 1.5 liters for mountain biking, as I live in the mountains, there's water everywhere, and I carry a filter. I am happy with the functionality of the whole set up.
