The Petzl Zipka is a unique headlamp that is well suited for backpacking. It packs small due to its innovative retractable cord headband, and is relatively light in weight at 2.3 oz or 64 grams. It is very easy to use, and offers considerably more lighting power than the ultralight 1 oz (27g) Petzl e+LITE; better battery life, and a much better spotlight beam, for only a little more weight and size. It also stacks up well against the Black Diamond Ion 1.9 oz (53g), with similar size, weight and battery life, but offering superior lighting in both spot and flood modes.
Ultralight fans will find the tiny Petzl e+LITE a better choice for backpacking, but for a lot of people, the extra punch of the Zipka is worth the extra weight.
