Camelbak Antidote Reservoir 100 oz
I bought this reservoir specifically for use in my Osprey Ariel 65 pack, but I did run into a few problems. Because my sleeping bag was so big (recently fixed that problem with a more compressible down bag), the designated space in the back of the pack was inhibited towards the bottom. Therefore, when I filled the reservoir, I couldn’t get it fully secured and clipped inside. I decided to take my smaller reservoir (70oz) which fit much better and worked out great with my pack. I also had a problem with the 100oz reservoir leaking from the mouthpiece. My husband later told me it was leaking because I neglected to put it in the off position, but I’m not so sure. I will definitely continue to use the Camelbak reservoirs as I have several already, but make sure you check that it fits your pack.
