Deuter · Ascender 13

340 grams, worn like a vest: 13 litres for running in the mountains.

On the descent, the load stays tight to your back: the wide shoulder straps wrap round your chest like a vest, and two sternum straps and an elastic cord pull everything in. The flasks sit up front, your phone in the zipped shoulder-strap pocket, and folded poles slide into a holster on the front of a shoulder strap, without you having to stop.

Trail running · Fast hiking · Mountains

Everything up front, nothing bouncing.

Deuter

Augsburg, 1898: mailbags first, then backpacks.

Since 1898

Hans Deuter opens a canvas workshop in Augsburg, Bavaria, and is soon sewing mailbags for the Royal Bavarian Post. In 1938, the first ascent of the Eiger North Face is made with a Deuter pack on the climber's back.

The mesh back

In 1984 came Aircomfort, a tensioned mesh that holds the pack away from your back. The Futura series took it up in 1999, and the Futura Pro carries it today.

Guaranteed, then repaired

Deuter guarantees its packs for 2 years against defects in materials and workmanship, on top of the legal guarantee, then repairs them at a shared cost. For a pack bought from Eiken, the claim goes through us.

Eiken's take

Why we chose it
You wear it like clothing: at 340 g you forget it's there, and the poles stowed on the shoulder strap don't break your rhythm on the climbs.
Worth knowing
Designed for 1 to 3 kg: load it beyond that and it doesn't run as well.
Who it's for
Trail runners heading out for a day in the mountains, and hikers who move fast and light.

Baptiste, Eiken

Questions

What are the dimensions and weight of the Ascender 13?

47 × 24 × 13 cm (height, width, depth, pack full) and 340 g, for 13 litres; 20 g less without the back foam. Recommended load: 1 to 3 kg.

Ascender 13 or Ascender 7?

Same vest, same pockets, same pole holster. The 7-litre weighs 315 g and takes a hydration reservoir up to 2 L, for an outing of a few hours; the 13-litre adds room for a jacket and a warm layer, and a reservoir up to 3 L, for the whole day.

Which hydration reservoir fits in the Ascender 13?

A reservoir of up to 3 litres, in the stretch mesh inner compartment. The shoulder-strap pockets also take two soft flasks.

How do I adjust the Ascender 13 so it doesn't move when I run?

Tighten the two sternum straps, then the elastic cord on the shoulder straps and the load lifters; the side compression straps pull the contents in when the pack isn't full.

Is the Ascender 13 waterproof?

No, it isn't made for rain: in steady rain, water gets in through the seams and zips. Put anything that mustn't get wet in a pouch.
