The double-wall stainless steel bottle ensures a pure taste with no flavor transfer, while the versatile design includes both a wide mouth cap and a spout cap for easy hydration on the go.
It's comfy since the strap comes with a pad. You can mount it to your pack. Additionally you could almost use the sling it comes with to sling your rifle. I don't know how much it's rated to hold but the pad is quite comfy.
