Osprey 2L HydraForm™ Nalgene Reservoir Bladder

between a layer of nylon fabric and the reservoir back. This forces the reservoir to conform to the back’s complex shape, even when full. The result is a more precise, stable and comfortable fit. Additionally, this reservoir has a rigid handle/spine that stabilizes the load of the water while also serving as a more convenient design to slide the reservoir into the pack

Nalgene Tech info:

Q: Is it okay to put iodine tablets in my reservoir?
A: Yes. For more thorough dissolution of the tablets, and for best mixing of the water you are trying to disinfect, it is recommended that you mix first in a bottle, then pour into your reservoir. Regardless of your approach, iodine is OK to use in your reservoir.

Q: What precisely is the "anti-microbial formula to prevent bacteria and mold"? 
A: Nalgene® reservoir film is treated with Aquaguard™. Aquaguard™ is the trade name for an FDA-approved anti-microbial which uses a silver and zinc composition to inhibit the growth of bacteria and mold, while offering carefree maintenance and odor control. 

Nalgene® recently communicated the following information as it relates to Aquaguard™ :

“You may have heard recently that the Food and Drug Administration said new research raises "valid concerns" about the possible health effects of Triclosan, a chemical commonly used for its antibacterial properties in a wide range of consumer products.

Aquaguard™, the anti-microbial formula used in Nalgene reservoirs and hose assemblies, does not contain Triclosan, and never has.”

Q: What precisely is the material that is in contact with the water? 
A: FDA-approved EVA film with 1% antimicrobial
