At the beginning of the bottle smells something clear, it is indeed new, but apart from the strong smell of neoprene, which is about to once a week soaking and continuous Auslüftens disappears, the bottle is really great! It is very light and the adjustable shoulder strap makes hiking really comfortable. Since the aluminum is coated on the inside, you could also acidic liquids into empty (eg aluminum tolerates no fruit).
One point I draw from, since the product at the beginning so stank. If that would go, they would have the neoprene and the bottle to let evaporate after the coating before it wraps.
