Review: It's a fuel bottle, what more can I say... it hold fuel well. I've had a 20 oz. one for about 5 years now, without any dents or cracks. They're a bit more expensive than I'd like, but not too bad.
Review: MSR fuel bottles come in different sizes varying from as little as 11oz up to 30oz. A sturdy bottle helps from punctures. Capable of carrying just about any fuel you'll need on a backpacking/camping trip. I own the 20oz. and it stands 8" So expect it to take up the room of a water bottle. Sounds like common sense but make sure the cap is on tight or you'll regret it. Don't have an exact weight but around 2oz empty.
