High-quality tension straps from American Hollis. Simple buckles with a plastic buckle tend to break in the cold, or just generally don't lock well enough around the bottle. Hollis buckles with a solid acid-resistant steel buckle withstand both a lot of beating and lock down effectively and easily.
The package also comes with an anti-slip rubber ring that you can put on the tension band, so the point against the bottle will not move at all.
The buckle fits all standard webbing and nylon bands with a width of 5 cm. The nylon webbing itself in the package is also extra solid, and feels both soft and feels more durable than cheap "stiff" webbing.
